* Omitted or undefined options will leave the corresponding configuration values unchanged.
*
* @param {Object=} config - The configuration object. May only contain the options that need to be
* updated. Supported keys:
*
* * `objectMaxDepth` **{Number}** - The max depth for stringifying objects. Setting to a
* non-positive or non-numeric value, removes the max depth limit.
* Default: 5
*
* * `urlErrorParamsEnabled` **{Boolean}** - Specifies whether the generated error url will
* contain the parameters of the thrown error. Disabling the parameters can be useful if the
* generated error url is very long.
*
* Default: true. When used without argument, it returns the current value.

* This object provides a utility for producing rich Error messages within

*
* var exampleMinErr = minErr('example');
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
*
* The above creates an instance of minErr in the example namespace. The
* resulting error will have a namespaced error code of example.one. The
* resulting error will replace {0} with the value of foo, and {1} with the
* value of bar. The object is not restricted in the number of arguments it can
* take.
*
* If fewer arguments are specified than necessary for interpolation, the extra
* interpolation markers will be preserved in the final string.
*
* Since data will be parsed statically during a build step, some restrictions
* are applied with respect to how minErr instances are created and called.
* Instances should have names of the form namespaceMinErr for a minErr created
* using minErr('namespace'). Error codes, namespaces and template strings
* should all be static strings, not variables or general expressions.
*
* @param {string} module The namespace to use for the new minErr instance.

* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
* created in "strict-di" mode. This means that the application will fail to invoke functions which

* in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
* tracking down the root of these bugs.
*
* @description
*
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
* designates the **root element** of the application and is typically placed near the root element
* of the page - e.g. on the `` or `` tags.
*
* There are a few things to keep in mind when using `ngApp`:
* - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
* found in the document will be used to define the root element to auto-bootstrap as an
* application. To run multiple applications in an HTML document you must manually bootstrap them using
* {@link angular.bootstrap} instead.
* - AngularJS applications cannot be nested within each other.
* - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
* This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
* {@link ngRoute.ngView `ngView`}.
* Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
* causing animations to stop working and making the injector inaccessible from outside the app.
*
* You can specify an **AngularJS module** to be used as the root module for the application. This
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
* should contain the application code needed or have dependencies on other modules that will
* contain the code. See {@link angular.module} for more information.
*
* In the example below if the `ngApp` directive were not placed on the `html` element then the
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
* would not be resolved to `3`.
*
* @example
*
* ### Simple Usage
*
* `ngApp` is the easiest, and most common way to bootstrap an application.
*
I can add: {{a}} + {{b}} = {{ a+b }}
angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
$scope.a = 1;
$scope.b = 2;
});
*
* @example
*
* ### With `ngStrictDi`
*
* Using `ngStrictDi`, you would see something like this:
*
I can add: {{a}} + {{b}} = {{ a+b }}
This renders because the controller does not fail to
instantiate, by using explicit annotation style (see
script.js for details)
Name:
Hello, {{name}}!
This renders because the controller does not fail to
instantiate, by using explicit annotation style
(see script.js for details)
I can add: {{a}} + {{b}} = {{ a+b }}
The controller could not be instantiated, due to relying
on automatic function annotations (which are disabled in
strict mode). As such, the content of this section is not
interpolated, and there should be an error in your web console.
angular.module('ngAppStrictDemo', [])
// BadController will fail to instantiate, due to relying on automatic function annotation,
// rather than an explicit annotation
.controller('BadController', function($scope) {
$scope.a = 1;
$scope.b = 2;

// Unlike BadController, GoodController1 and GoodController2 will not fail to be instantiated,
// due to using explicit annotations using the array style and $inject property, respectively.

* The `angular.module` is a global place for creating, registering and retrieving AngularJS
* modules.
* All modules (AngularJS core or 3rd party) that should be available to an application must be
* registered using this mechanism.
*
* Passing one argument retrieves an existing {@link angular.Module},
* whereas passing more than one argument creates a new {@link angular.Module}
*
*
* # Module
*
* A module is a collection of services, directives, controllers, filters, and configuration information.
* `angular.module` is used to configure the {@link auto.$injector $injector}.
*
* ```js
* // Create a new module
* var myModule = angular.module('myModule', []);
*
* // register a new service
* myModule.value('appName', 'MyCoolApp');
*
* // configure existing services inside initialization blocks.
* myModule.config(['$locationProvider', function($locationProvider) {
* // Configure existing providers
* $locationProvider.hashPrefix('!');
* }]);
* ```
*
* Then you can create an injector and load your modules like this:
*
* ```js
* var injector = angular.injector(['ng', 'myModule'])
* ```
*
* However it's more likely that you'll just use
* {@link ng.directive:ngApp ngApp} or
* {@link angular.bootstrap} to simplify this process for you.
*
* @param {!string} name The name of the module to create or retrieve.
* @param {!Array.=} requires If specified then new module is being created. If
* unspecified then the module is being retrieved for further configuration.
* @param {Function=} configFn Optional configuration function for the module. Same as
* {@link angular.Module#config Module#config()}.
* @returns {angular.Module} new module with the {@link angular.Module} api.

/**
* @ngdoc function
* @name angular.element
* @module ng
* @kind function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
*
* If jQuery is available, `angular.element` is an alias for the
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
* delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
*
* jqLite is a tiny, API-compatible subset of jQuery that allows
* AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
* commonly needed functionality with the goal of having a very small footprint.
*
* To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
* {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
* specific version of jQuery if multiple versions exist on the page.
*
*
**Note:** All element references in AngularJS are always wrapped with jQuery or
* jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
*
*
**Note:** Keep in mind that this function will not find elements
* by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
* or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
*
* ## AngularJS's jqLite
* jqLite provides only the following jQuery methods:
*
* - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
* - [`after()`](http://api.jquery.com/after/)
* - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
* so will not work correctly when invoked on a jqLite object containing more than one DOM node
* - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
* - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors
* - [`clone()`](http://api.jquery.com/clone/)
* - [`contents()`](http://api.jquery.com/contents/)
* - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
* As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
* - [`data()`](http://api.jquery.com/data/)
* - [`detach()`](http://api.jquery.com/detach/)
* - [`empty()`](http://api.jquery.com/empty/)
* - [`eq()`](http://api.jquery.com/eq/)
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
* - [`hasClass()`](http://api.jquery.com/hasClass/)
* - [`html()`](http://api.jquery.com/html/)
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
* - [`prepend()`](http://api.jquery.com/prepend/)
* - [`prop()`](http://api.jquery.com/prop/)
* - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
* - [`remove()`](http://api.jquery.com/remove/)
* - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
* - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
* - [`removeData()`](http://api.jquery.com/removeData/)
* - [`replaceWith()`](http://api.jquery.com/replaceWith/)
* - [`text()`](http://api.jquery.com/text/)
* - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
* - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
* - [`val()`](http://api.jquery.com/val/)
* - [`wrap()`](http://api.jquery.com/wrap/)
*
* jqLite also provides a method restoring pre-1.8 insecure treatment of XHTML-like tags.
* This legacy behavior turns input like `` to ``
* instead of `
` like version 1.8 & newer do. To restore it, invoke:
* ```js
* angular.UNSAFE_restoreLegacyJqLiteXHTMLReplacement();
* ```
* Note that this only patches jqLite. If you use jQuery 3.5.0 or newer, please read the
* [jQuery 3.5 upgrade guide](https://jquery.com/upgrade-guide/3.5/) for more details
* about the workarounds.
*
* ## jQuery/jqLite Extras
* AngularJS also provides the following additional methods and events to both jQuery and jqLite:
*
* ### Events
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
* element before it is removed.
*
* ### Methods
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
* retrieves controller associated with the `ngController` directive. If `name` is provided as
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
* `'ngModel'`).
* - `injector()` - retrieves the injector of the current element or its parent.
* - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
* element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
* be enabled.
* - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
* current element. This getter should be used only on elements that contain a directive which starts a new isolate
* scope. Calling `scope()` on this element always returns the original non-isolate scope.
* Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
* parent element is reached.
*
* @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
* https://github.com/angular/angular.js/issues/14251 for more information.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.

/**
* @ngdoc service
* @name $injector
*
* @description
*
* `$injector` is used to retrieve object instances as defined by
* {@link auto.$provide provider}, instantiate types, invoke methods,
* and load modules.
*
* The following always holds true:
*
* ```js
* var $injector = angular.injector();
* expect($injector.get('$injector')).toBe($injector);
* expect($injector.invoke(function($injector) {
* return $injector;
* })).toBe($injector);
* ```
*
* ## Injection Function Annotation
*
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
* following are all valid ways of annotating function with injection arguments and are equivalent.
*
* ```js
* // inferred (only works if code not minified/obfuscated)
* $injector.invoke(function(serviceA){});
*
* // annotated
* function explicit(serviceA) {};
* explicit.$inject = ['serviceA'];
* $injector.invoke(explicit);
*
* // inline
* $injector.invoke(['serviceA', function(serviceA){}]);
* ```
*
* ### Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition
* can then be parsed and the function arguments can be extracted. This method of discovering
* annotations is disallowed when the injector is in strict mode.
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
* argument names.
*
* ### `$inject` Annotation
* By adding an `$inject` property onto a function the injection parameters can be specified.
*
* ### Inline
* As an array of injection names, where the last item in the array is the function to call.

/**
* @ngdoc method
* @name $injector#annotate
*
* @description
* Returns an array of service names which the function is requesting for injection. This API is
* used by the injector to determine which services need to be injected into the function when the
* function is invoked. There are three ways in which the function can be annotated with the needed
* dependencies.
*
* #### Argument names
*
* The simplest form is to extract the dependencies from the arguments of the function. This is done
* by converting the function into a string using `toString()` method and extracting the argument
* names.
* ```js
* // Given
* function MyController($scope, $route) {
* // ...
* }
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* You can disallow this method by using strict injection mode.
*
* This method does not work with code minification / obfuscation. For this reason the following
* annotation strategies are supported.
*
* #### The `$inject` property
*
* If a function has an `$inject` property and its value is an array of strings, then the strings
* represent names of services to be injected into the function.
* ```js
* // Given
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
* // ...
* }
* // Define function dependencies
* MyController['$inject'] = ['$scope', '$route'];
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* #### The array notation
*
* It is often desirable to inline Injected functions and that's when setting the `$inject` property
* is very inconvenient. In these situations using the array notation to specify the dependencies in
* a way that survives minification is a better choice:
*
* ```js
* // We wish to write this (not minification / obfuscation safe)
* injector.invoke(function($compile, $rootScope) {
* // ...
* });
*
* // We are forced to write break inlining
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
* // ...
* };
* tmpFn.$inject = ['$compile', '$rootScope'];
* injector.invoke(tmpFn);
*
* // To better support inline function the inline annotation is supported
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
* // ...
* }]);
*
* // Therefore
* expect(injector.annotate(
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
* ).toEqual(['$compile', '$rootScope']);
* ```
*
* @param {Function|Array.} fn Function for which dependent service names need to
* be retrieved as described above.
*
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
*
* @returns {Array.} The names of the services which the function requires.

*
* Add the specified modules to the current injector.
*
* This method will add each of the injectables to the injector and execute all of the config and run

*
* * The application developer is responsible for loading the code containing the modules; and for
* ensuring that lazy scripts are not downloaded and executed more often that desired.
* * Previously compiled HTML will not be affected by newly loaded directives, filters and components.
* * Modules cannot be unloaded.
*
* You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded
* into the injector, which may indicate whether the script has been executed already.
*
* @example

*
* The {@link auto.$provide $provide} service has a number of methods for registering components
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on
* {@link angular.Module}.
*
* An AngularJS **service** is a singleton object created by a **service factory**. These **service
* factories** are functions which, in turn, are created by a **service provider**.
* The **service providers** are constructor functions. When instantiated they must contain a
* property called `$get`, which holds the **service factory** function.
*
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the
* correct **service provider**, instantiating it and then calling its `$get` **service factory**
* function to get the instance of the **service**.
*
* Often services have no configuration options and there is no need to add methods to the service
* provider. The provider will be no more than a constructor function with a `$get` property. For
* these cases the {@link auto.$provide $provide} service has additional helper methods to register
* services without specifying a provider.
*
* * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
* {@link auto.$injector $injector}
* * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
* providers and services.
* * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
* services, not providers.
* * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
* that will be wrapped in a **service provider** object, whose `$get` property will contain the
* given factory function.
* * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate
* a new object using the given constructor function.

/**
* @ngdoc method
* @name $provide#provider
* @description
*
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
* are constructor functions, whose instances are responsible for "providing" a factory for a
* service.
*
* Service provider names start with the name of the service they provide followed by `Provider`.
* For example, the {@link ng.$log $log} service has a provider called
* {@link ng.$logProvider $logProvider}.
*
* Service provider objects can have additional methods which allow configuration of the provider
* and its service. Importantly, you can configure what kind of service is created by the `$get`
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
* method {@link ng.$logProvider#debugEnabled debugEnabled}
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
* console or not.
*
* It is possible to inject other providers into the provider function,
* but the injected provider must have been defined before the one that requires it.
*
* @param {string} name The name of the instance. NOTE: the provider will be available under `name +
'Provider'` key.
* @param {(Object|function())} provider If the provider is:
*
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
* - `Constructor`: a new instance of the provider will be created using
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
*
* @returns {Object} registered provider instance
* @example
*
* The following example shows how to create a simple event tracking service and register it using
* {@link auto.$provide#provider $provide.provider()}.
*
* ```js
* // Define the eventTracker provider
* function EventTrackerProvider() {
* var trackingUrl = '/track';
*
* // A provider method for configuring where the tracked events should been saved
* this.setTrackingUrl = function(url) {
* trackingUrl = url;
* };
*
* // The service factory function
* this.$get = ['$http', function($http) {
* var trackedEvents = {};
* return {
* // Call this to track an event
* event: function(event) {
* var count = trackedEvents[event] || 0;
* count += 1;
* trackedEvents[event] = count;
* return count;
* },
* // Call this to save the tracked events to the trackingUrl
* save: function() {
* $http.post(trackingUrl, trackedEvents);
* }
* };
* }];
* }
*
* describe('eventTracker', function() {
* var postSpy;
*
* beforeEach(module(function($provide) {
* // Register the eventTracker provider
* $provide.provider('eventTracker', EventTrackerProvider);
* }));
*
* beforeEach(module(function(eventTrackerProvider) {
* // Configure eventTracker provider
* eventTrackerProvider.setTrackingUrl('/custom-track');
* }));
*
* it('tracks events', inject(function(eventTracker) {
* expect(eventTracker.event('login')).toEqual(1);
* expect(eventTracker.event('login')).toEqual(2);
* }));
*
* it('saves to the tracking url', inject(function(eventTracker, $http) {
* postSpy = spyOn($http, 'post');
* eventTracker.event('login');
* eventTracker.save();
* expect(postSpy).toHaveBeenCalled();
* expect(postSpy.mostRecentCall.args[0]).not.toEqual('/track');
* expect(postSpy.mostRecentCall.args[0]).toEqual('/custom-track');
* expect(postSpy.mostRecentCall.args[1]).toEqual({ 'login': 1 });
* }));
* });
* ```

*
* Value services are similar to constant services, except that they cannot be injected into a

/**
* @ngdoc method
* @name $provide#decorator
* @description
*
* Register a **decorator function** with the {@link auto.$injector $injector}. A decorator function
* intercepts the creation of a service, allowing it to override or modify the behavior of the
* service. The return value of the decorator function may be the original service, or a new service
* that replaces (or wraps and delegates to) the original service.
*
* You can find out more about using decorators in the {@link guide/decorators} guide.
*
* @param {string} name The name of the service to decorate.
* @param {Function|Array.} decorator This function will be invoked when the service needs to be
* provided and should return the decorated service instance. The function is called using
* the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
* Local injection arguments:
*
* * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
* decorated or delegated to.
*
* @example
* Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
* calls to {@link ng.$log#error $log.warn()}.

* It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
* match any anchor whenever it changes. This can be disabled by calling
* {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
*
* Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a

* positioned elements at the top of the page, such as navbars, headers etc.
*
* `yOffset` can be specified in various ways:
* - **number**: A fixed number of pixels to be used as offset.
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
* a number representing the offset (in pixels).
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
* the top of the page to the element's bottom will be used as offset.
* **Note**: The element will be taken into account only as long as its `position` is set to
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
* their height and/or positioning according to the viewport's size.
*
*
*
* In order for `yOffset` to work properly, scrolling should take place on the document's root and
* not some child element.

* Sets and/or returns the custom filter function that is used to "filter" animations, i.e.
* determine if an animation is allowed or not. When no filter is specified (the default), no
* animation will be blocked. Setting the `customFilter` value will only allow animations for
* which the filter function's return value is truthy.
*
* This allows to easily create arbitrarily complex rules for filtering animations, such as
* allowing specific events only, or enabling animations on specific subtrees of the DOM, etc.
* Filtering animations can also boost performance for low-powered devices, as well as
* applications containing a lot of structural operations.
*
*
* **Best Practice:**
* Keep the filtering function as lean as possible, because it will be called for each DOM
* action (e.g. insertion, removal, class change) performed by "animation-aware" directives.
* See {@link guide/animations#which-directives-support-animations- here} for a list of built-in
* directives that support animations.
* Performing computationally expensive or time-consuming operations on each call of the
* filtering function can make your animations sluggish.
*
*
* **Note:** If present, `customFilter` will be checked before
* {@link $animateProvider#classNameFilter classNameFilter}.
*
* @param {Function=} filterFn - The filter function which will be used to filter all animations.
* If a falsy value is returned, no animation will be performed. The function will be called

* - **node** `{DOMElement}` - The DOM element to be animated.
* - **event** `{String}` - The name of the animation event (e.g. `enter`, `leave`, `addClass`

* their DOM-related operations (enter, leave and move). Other directives such as `ngClass`,
* `ngShow`, `ngHide` and `ngMessages` also provide support for animations.

* $animate.on('enter', container,

* }
* );
* ```
*
*
* **Note**: Generally, the events that are fired correspond 1:1 to `$animate` method names,
* e.g. {@link ng.$animate#addClass addClass()} will fire `addClass`, and {@link ng.ngClass}
* will fire `addClass` if classes are added, and `removeClass` if classes are removed.
* However, there are two exceptions:
*
*
*
if both an {@link ng.$animate#addClass addClass()} and a
* {@link ng.$animate#removeClass removeClass()} action are performed during the same
* animation, the event fired will be `setClass`. This is true even for `ngClass`.
*
an {@link ng.$animate#animate animate()} call that adds and removes classes will fire
* the `setClass` event, but if it either removes or adds classes,
* it will fire `animate` instead.
*
*
*

* @param {DOMElement} container the container element that will capture each of the animation events that are fired on itself
* as well as among its children
* @param {Function} callback the callback function that will be fired when the listener is triggered.
*
* The arguments present in the callback function are:
* * `element` - The captured DOM element that the animation was fired on.
* * `phase` - The phase of the animation. The two possible phases are **start** (when the animation starts) and **close** (when it ends).
* * `data` - an object with these properties:
* * addClass - `{string|null}` - space-separated CSS classes to add to the element
* * removeClass - `{string|null}` - space-separated CSS classes to remove from the element
* * from - `{Object|null}` - CSS properties & values at the beginning of the animation
* * to - `{Object|null}` - CSS properties & values at the end of the animation
*
* Note that the callback does not trigger a scope digest. Wrap your call into a

/**
* @ngdoc service
* @name $sce
* @kind function
*
* @description
*
* `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
*
* ## Strict Contextual Escaping
*
* Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
* trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
* (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
*
* ### Overview
*
* To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
* HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
* run security checks on them (sanitizations, trusted URL resource, depending on context), or throw
* when it cannot guarantee the security of the result. That behavior depends strongly on contexts:
* HTML can be sanitized, but template URLs cannot, for instance.
*
* To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
* we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
* before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
* render the input as-is, you will need to mark it as trusted for that context before attempting
* to bind it.
*
* As of version 1.2, AngularJS ships with SCE enabled by default.
*
* ### In practice
*
* Here's an example of a binding in a privileged context:
*
* ```
*
*
* ```
*
* Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
* disabled, this application allows the user to render arbitrary HTML into the DIV, which would
* be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
* articles, etc. via bindings. (HTML is just one example of a context where rendering user
* controlled input creates security vulnerabilities.)
*
* For the case of HTML, you might use a library, either on the client side, or on the server side,
* to sanitize unsafe HTML before binding to the value and rendering it in the document.
*
* How would you ensure that every place that used these types of bindings was bound to a value that
* was sanitized by your library (or returned as safe for rendering by your server?) How can you
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
* properties/fields and forgot to update the binding to the sanitized value?
*
* To be secure by default, AngularJS makes sure bindings go through that sanitization, or
* any similar validation process, unless there's a good reason to trust the given value in this
* context. That trust is formalized with a function call. This means that as a developer, you
* can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
* you just need to ensure the values you mark as trusted indeed are safe - because they were
* received from your server, sanitized by your library, etc. You can organize your codebase to
* help with this - perhaps allowing only the files in a specific directory to do this.
* Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
* becomes a more manageable task.
*
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
* (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
* build the trusted versions of your values.
*
* ### How does it work?
*
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
* $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
* a way to enforce the required security context in your data sink. Directives use {@link
* ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
* the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
* when binding without directives, AngularJS will understand the context of your bindings
* automatically.
*
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
* ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
* simplified):
*
* ```
* var ngBindHtmlDirective = ['$sce', function($sce) {
* return function(scope, element, attr) {
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
* element.html(value || '');
* });
* };
* }];
* ```
*
* ### Impact on loading templates
*
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
* `templateUrl`'s specified by {@link guide/directive directives}.
*
* By default, AngularJS only loads templates from the same domain and protocol as the application
* document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
* protocols, you may either add them to the {@link ng.$sceDelegateProvider#trustedResourceUrlList
* trustedResourceUrlList} or {@link ng.$sce#trustAsResourceUrl wrap them} into trusted values.
*
* *Please note*:
* The browser's
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
* policy apply in addition to this and may further restrict whether the template is successfully
* loaded. This means that without the right CORS policy, loading templates from a different domain
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some
* browsers.
*
* ### This feels like too much overhead
*
* It's important to remember that SCE only applies to interpolation expressions.
*
* If your expressions are constant literals, they're automatically trusted and you don't need to
* call `$sce.trustAs` on them (e.g.
* ``) just works (remember to include the
* `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
* when binding untrusted values to `$sce.HTML` context.
* AngularJS provides an implementation in `angular-sanitize.js`, and if you
* wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
* your application.
*
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
* templates in `ng-include` from your application's domain without having to even know about SCE.
* It blocks loading templates from other domains or loading templates over http from an https
* served document. You can change these by setting your own custom {@link
* ng.$sceDelegateProvider#trustedResourceUrlList trusted resource URL list} and {@link
* ng.$sceDelegateProvider#bannedResourceUrlList banned resource URL list} for matching such URLs.
*
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an
* application that's secure and can be audited to verify that with much more ease than bolting
* security onto an application later.
*
*
* ### What trusted context types are supported?
*
* | Context | Notes |
* |---------------------|----------------|
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings.

* | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed.

*
*
*
* Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
* interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
*
* **As of 1.7.0, this is no longer the case.**
*
* Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
* (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
* service evaluates the expressions.
*
*
* There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
* functions aren't useful yet. This might evolve.
*
* ### Format of items in {@link ng.$sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList}/{@link ng.$sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList}
*
* Each element in these arrays must be one of the following:
*
* - **'self'**
* - The special **string**, `'self'`, can be used to match against all URLs of the **same
* domain** as the application document using the **same protocol**.
* - **String** (except the special value `'self'`)
* - The string is matched against the full *normalized / absolute URL* of the resource
* being tested (substring matches are not good enough.)
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
* match themselves.
* - `*`: matches zero or more occurrences of any character other than one of the following 6
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use
* for matching resource URL lists.
* - `**`: matches zero or more occurrences of *any* character. As such, it's not
* appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
* not have been the intention.) Its usage at the very end of the path is ok. (e.g.
* http://foo.example.com/templates/**).
* - **RegExp** (*see caveat below*)
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should
* have good test coverage). For instance, the use of `.` in the regex is correct only in a
* small number of cases. A `.` character in the regex used when matching the scheme or a
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It
* is highly recommended to use the string patterns and only fall back to regular expressions
* as a last resort.
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is
* matched against the **entire** *normalized / absolute URL* of the resource being tested
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
* present on the RegExp (such as multiline, global, ignoreCase) are ignored.
* - If you are generating your JavaScript from some other templating engine (not
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
* remember to escape your regular expression (and be aware that you might need more than
* one level of escaping depending on your templating engine and the way you interpolated
* the value.) Do make use of your platform's escaping mechanism as it might be good
* enough before coding your own. E.g. Ruby has
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
* Javascript lacks a similar built in function for escaping. Take a look at Google
* Closure library's [goog.string.regExpEscape(s)](
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
*
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.
*
* ### Show me an example using SCE.
*
*
*
*
*
* User comments
* By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
* $sanitize is available. If $sanitize isn't available, this results in an error instead of an
* exploit.
*
*
* {{userComment.name}}:
*
*
*
*
*
*
*
*
* angular.module('mySceApp', ['ngSanitize'])
* .controller('AppController', ['$http', '$templateCache', '$sce',
* function AppController($http, $templateCache, $sce) {
* var self = this;
* $http.get('test_data.json', {cache: $templateCache}).then(function(response) {
* self.userComments = response.data;
* });
* self.explicitlyTrustedHtml = $sce.trustAsHtml(
* 'Hover over this text.');
* }]);
*
*
*
* [
* { "name": "Alice",
* "htmlComment":
* "Is anyone reading this?"
* },
* { "name": "Bob",
* "htmlComment": "Yes! Am I the only other one?"
* }
* ]
*
*
*
* describe('SCE doc demo', function() {
* it('should sanitize untrusted values', function() {
* expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML'))
* .toBe('Is anyone reading this?');
* });
*
* it('should NOT sanitize explicitly trusted values', function() {
* expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe(
* 'Hover over this text.');
* });
* });
*
*
*
*
*
* ## Can I disable SCE completely?
*
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
* for little coding overhead. It will be much harder to take an SCE disabled application and
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
* for cases where you have a lot of existing code that was written before SCE was introduced and
* you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
* you are writing a library, you will cause security bugs applications using it.
*
* That said, here's how you can completely disable SCE:
*
* ```
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
* // Completely disable SCE. For demonstration purposes only!
* // Do not use in new projects or libraries.
* $sceProvider.enabled(false);
* });
* ```
*

var enabled = true;

/* Design notes on the default implementation for SCE.
*
* The API contract for the SCE delegate
* -------------------------------------
* The SCE delegate object must provide the following 3 methods:
*
* - trustAs(contextEnum, value)
* This method is used to tell the SCE service that the provided value is OK to use in the
* contexts specified by contextEnum. It must return an object that will be accepted by
* getTrusted() for a compatible contextEnum and return this value.
*
* - valueOf(value)
* For values that were not produced by trustAs(), return them as is. For values that were
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if
* trustAs is wrapping the given values into some type, this operation unwraps it when given
* such a value.
*
* - getTrusted(contextEnum, value)
* This function should return the value that is safe to use in the context specified by
* contextEnum or throw and exception otherwise.
*
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
* opaque or wrapped in some holder object. That happens to be an implementation detail. For
* instance, an implementation could maintain a registry of all trusted objects by context. In
* such a case, trustAs() would return the same object that was passed in. getTrusted() would
* return the same object passed in if it was found in the registry under a compatible context or
* throw an exception otherwise. An implementation might only wrap values some of the time based
* on some criteria. getTrusted() might return a value and not throw an exception for special
* constants or objects even if not wrapped. All such implementations fulfill this contract.
*
*
* A note on the inheritance model for SCE contexts
* ------------------------------------------------
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
* is purely an implementation details.
*
* The contract is simply this:
*
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
* will also succeed.
*
* Inheritance happens to capture this in a natural way. In some future, we may not use
* inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
* be aware of this detail.

*
* Implementation Notes for non-IE browsers
* ----------------------------------------
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
* results both in the normalizing and parsing of the URL. Normalizing means that a relative
* URL will be resolved into an absolute URL in the context of the application document.
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
* properties are all populated to reflect the normalized URL. This approach has wide
* compatibility - Safari 1+, Mozilla 1+ etc. See
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
*
* Implementation Notes for IE
* ---------------------------
* IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
* browsers. However, the parsed components will not be set if the URL assigned did not specify
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
* work around that by performing the parsing in a 2nd step by taking a previously normalized
* URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
* properties such as protocol, hostname, port, etc.

* @ngdoc filter
* @name filter
* @kind function
*
* @description
* Selects a subset of items from `array` and returns it as a new array.
*
* @param {Array} array The source array.
*
* **Note**: If the array contains objects that reference themselves, filtering is not possible.
*
* @param {string|Object|function()} expression The predicate to be used for selecting items from
* `array`.
*
* Can be one of:
*
* - `string`: The string is used for matching against the contents of the `array`. All strings or
* objects with string properties in `array` that match this string will be returned. This also
* applies to nested object properties.
* The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
* which have property `name` containing "M" and property `phone` containing "1". A special
* property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
* against any property of the object or its nested object properties. That's equivalent to the
* simple substring match with a `string` as described above. The special property name can be
* overwritten, using the `anyPropertyKey` parameter.
* The predicate can be negated by prefixing the string with `!`.
* For example `{name: "!M"}` predicate will return an array of items which have property `name`
* not containing "M".
*
* Note that a named property will match properties on the same level only, while the special
* `$` property will match properties on the same level or deeper. E.g. an array item like
* `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
* **will** be matched by `{$: 'John'}`.
*
* - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
* The function is called for each element of the array, with the element, its index, and
* the entire array itself as arguments.
*
* The final result is an array of those elements that the predicate returned true for.
*
* @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
* determining if values retrieved using `expression` (when it is not a function) should be
* considered a match based on the expected value (from the filter expression) and actual
* value (from the object in the array).
*
* Can be one of:
*
* - `function(actual, expected)`:
* The function will be given the object value and the predicate value to compare and
* should return true if both values should be considered equal.
*
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
* This is essentially strict comparison of expected and actual.
*
* - `false`: A short hand for a function which will look for a substring match in a case
* insensitive way. Primitive values are converted to strings. Objects are not compared against
* primitives, unless they have a custom `toString` method (e.g. `Date` objects).
*
*
* Defaults to `false`.
*
* @param {string} [anyPropertyKey] The special property name that matches against any property.
* By default `$`.
*
* @example
Name
Phone
{{friend.name}}
{{friend.phone}}
Name
Phone
{{friendObj.name}}
{{friendObj.phone}}

* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
* * `'MMMM'`: Month in year (January-December)
* * `'MMM'`: Month in year (Jan-Dec)
* * `'MM'`: Month in year, padded (01-12)
* * `'M'`: Month in year (1-12)
* * `'LLLL'`: Stand-alone month in year (January-December)
* * `'dd'`: Day in month, padded (01-31)
* * `'d'`: Day in month (1-31)
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
* * `'EEE'`: Day in Week, (Sun-Sat)
* * `'HH'`: Hour in day, padded (00-23)
* * `'H'`: Hour in day (0-23)
* * `'hh'`: Hour in AM/PM, padded (01-12)
* * `'h'`: Hour in AM/PM, (1-12)
* * `'mm'`: Minute in hour, padded (00-59)
* * `'m'`: Minute in hour (0-59)
* * `'ss'`: Second in minute, padded (00-59)
* * `'s'`: Second in minute (0-59)
* * `'sss'`: Millisecond in second, padded (000-999)
* * `'a'`: AM/PM marker
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
* * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
* * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
* * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
* * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
*
* `format` string can also be one of the following predefined
* {@link guide/i18n localizable formats}:
*
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
* (e.g. Sep 3, 2010 12:05:08 PM)
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
* * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
* (e.g. Friday, September 3, 2010)
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
*
* `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
* `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
* (e.g. `"h 'o''clock'"`).
*
* Any other characters in the `format` string will be output as-is.
*
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
* specified in the string input, the time is considered to be in the local timezone.
* @param {string=} format Formatting rules (see Description). If not specified,
* `mediumDate` is used.
* @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
* continental US time zone abbreviations, but for general use, use a time zone offset, for
* example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)

/**
* @ngdoc filter
* @name orderBy
* @kind function
*
* @description
* Returns an array containing the items from the specified `collection`, ordered by a `comparator`
* function based on the values computed using the `expression` predicate.
*
* For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
* `[{id: 'bar'}, {id: 'foo'}]`.
*
* The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
* String, etc).
*
* The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
* for the preceding one. The `expression` is evaluated against each item and the output is used
* for comparing with other items.
*
* You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
* ascending order.
*
* The comparison is done using the `comparator` function. If none is specified, a default, built-in
* comparator is used (see below for details - in a nutshell, it compares numbers numerically and
* strings alphabetically).
*
* ### Under the hood
*
* Ordering the specified `collection` happens in two phases:
*
* 1. All items are passed through the predicate (or predicates), and the returned values are saved
* along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
* through a predicate that extracts the value of the `label` property, would be transformed to:
* ```
* {
* value: 'foo',
* type: 'string',
* index: ...
* }
* ```
* **Note:** `null` values use `'null'` as their type.
* 2. The comparator function is used to sort the items, based on the derived values, types and
* indices.
*
* If you use a custom comparator, it will be called with pairs of objects of the form
* `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
* (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
* second, or `1` otherwise.
*
* In order to ensure that the sorting will be deterministic across platforms, if none of the
* specified predicates can distinguish between two items, `orderBy` will automatically introduce a
* dummy predicate that returns the item's index as `value`.
* (If you are using a custom comparator, make sure it can handle this predicate as well.)
*
* If a custom comparator still can't distinguish between two items, then they will be sorted based
* on their index using the built-in comparator.
*
* Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
* value for an item, `orderBy` will try to convert that object to a primitive value, before passing
* it to the comparator. The following rules govern the conversion:
*
* 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
* used instead.
* (If the object has a `valueOf()` method that returns another object, then the returned object
* will be used in subsequent steps.)
* 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
* returns a primitive, its return value will be used instead.
* (If the object has a `toString()` method that returns another object, then the returned object
* will be used in subsequent steps.)
* 3. No conversion; the object itself is used.
*
* ### The default comparator
*
* The default, built-in comparator should be sufficient for most usecases. In short, it compares
* numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
* using their index in the original collection, sorts values of different types by type and puts
* `undefined` and `null` values at the end of the sorted list.
*
* More specifically, it follows these steps to determine the relative order of items:
*
* 1. If the compared values are of different types:
* - If one of the values is undefined, consider it "greater than" the other.
* - Else if one of the values is null, consider it "greater than" the other.
* - Else compare the types themselves alphabetically.
* 2. If both values are of type `string`, compare them alphabetically in a case- and
* locale-insensitive way.
* 3. If both values are objects, compare their indices instead.
* 4. Otherwise, return:
* - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
* - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
* - `1`, otherwise.
*
* **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
* saved as numbers and not strings.
* **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than"
* any other value (with undefined "greater than" null). This effectively means that `null`
* and `undefined` values end up at the end of a list sorted in ascending order.
* **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.
*
* @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
* @param {(Function|string|Array.)=} expression - A predicate (or list of
* predicates) to be used by the comparator to determine the order of elements.
*
* Can be one of:
*
* - `Function`: A getter function. This function will be called with each item as argument and
* the return value will be used for sorting.
* - `string`: An AngularJS expression. This expression will be evaluated against each item and the
* result will be used for sorting. For example, use `'label'` to sort by a property called
* `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
* property.
* (The result of a constant expression is interpreted as a property name to be used for
* comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
* property called `special name`.)
* An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
* ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
* (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
* - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
* relative order of two items, the next predicate is used as a tie-breaker.
*
* **Note:** If the predicate is missing or empty then it defaults to `'+'`.
*
* @param {boolean=} reverse - If `true`, reverse the sorting order.
* @param {(Function)=} comparator - The comparator function used to determine the relative order of
* value pairs. If omitted, the built-in comparator will be used.
*
* @returns {Array} - The sorted array.
*
*
* @example
* ### Ordering a table with `ngRepeat`
*
* The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
* age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
* it defaults to the built-in comparator.
*
