-/**
- `Promise.all` accepts an array of promises, and returns a new promise which
- is fulfilled with an array of fulfillment values for the passed promises, or
- rejected with the reason of the first passed promise to be rejected. It casts all
- elements of the passed iterable to promises as it runs this algorithm.
-
- Example:
-
- ```javascript
- let promise1 = resolve(1);
- let promise2 = resolve(2);
- let promise3 = resolve(3);
- let promises = [ promise1, promise2, promise3 ];
-
- Promise.all(promises).then(function(array){
- // The array here would be [ 1, 2, 3 ];
- });
- ```
-
- If any of the `promises` given to `all` are rejected, the first promise
- that is rejected will be given as an argument to the returned promises's
- rejection handler. For example:
-
- Example:
-
- ```javascript
- let promise1 = resolve(1);
- let promise2 = reject(new Error("2"));
- let promise3 = reject(new Error("3"));
- let promises = [ promise1, promise2, promise3 ];
-
- Promise.all(promises).then(function(array){
- // Code here never runs because there are rejected promises!
- }, function(error) {
- // error.message === "2"
- });
- ```
-
- @method all
- @static
- @param {Array} entries array of promises
- @param {String} label optional string for labeling the promise.
- Useful for tooling.
- @return {Promise} promise that is fulfilled when all `promises` have been
- fulfilled, or rejected if any of them become rejected.

-
-/**
- `Promise.race` returns a new promise which is settled in the same way as the
- first passed promise to settle.
-
- Example:
-
- ```javascript
- let promise1 = new Promise(function(resolve, reject){
- setTimeout(function(){
- resolve('promise 1');
- }, 200);
- });
-
- let promise2 = new Promise(function(resolve, reject){
- setTimeout(function(){
- resolve('promise 2');
- }, 100);
- });
-
- Promise.race([promise1, promise2]).then(function(result){
- // result === 'promise 2' because it was resolved before promise1
- // was resolved.
- });
- ```
-
- `Promise.race` is deterministic in that only the state of the first
- settled promise matters. For example, even if other promises given to the
- `promises` array argument are resolved, but the first settled promise has
- become rejected before the other promises became fulfilled, the returned
- promise will become rejected:
-
- ```javascript
- let promise1 = new Promise(function(resolve, reject){
- setTimeout(function(){
- resolve('promise 1');
- }, 200);
- });
-
- let promise2 = new Promise(function(resolve, reject){
- setTimeout(function(){
- reject(new Error('promise 2'));
- }, 100);
- });
-
- Promise.race([promise1, promise2]).then(function(result){
- // Code here never runs
- }, function(reason){
- // reason.message === 'promise 2' because promise 2 became rejected before
- // promise 1 became fulfilled
- });
- ```
-

-
- ```javascript
- Promise.race([ajax('foo.json'), timeout(5000)])
- ```

-/**
- Promise objects represent the eventual result of an asynchronous operation. The
- primary way of interacting with a promise is through its `then` method, which
- registers callbacks to receive either a promise's eventual value or the reason
- why the promise cannot be fulfilled.
-
- Terminology
- -----------
-
- - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- - `thenable` is an object or function that defines a `then` method.
- - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- - `exception` is a value that is thrown using the throw statement.
- - `reason` is a value that indicates why a promise was rejected.
- - `settled` the final resting state of a promise, fulfilled or rejected.
-
- A promise can be in one of three states: pending, fulfilled, or rejected.
-
- Promises that are fulfilled have a fulfillment value and are in the fulfilled
- state. Promises that are rejected have a rejection reason and are in the
- rejected state. A fulfillment value is never a thenable.
-
- Promises can also be said to *resolve* a value. If this value is also a
- promise, then the original promise's settled state will match the value's
- settled state. So a promise that *resolves* a promise that rejects will
- itself reject, and a promise that *resolves* a promise that fulfills will
- itself fulfill.
-
-
- Basic Usage:
- ------------
-
- ```js
- let promise = new Promise(function(resolve, reject) {
- // on success
- resolve(value);
-
- // on failure
- reject(reason);
- });
-
- promise.then(function(value) {
- // on fulfillment
- }, function(reason) {
- // on rejection
- });
- ```
-
- Advanced Usage:
- ---------------
-
- Promises shine when abstracting away asynchronous interactions such as
- `XMLHttpRequest`s.
-
- ```js
- function getJSON(url) {
- return new Promise(function(resolve, reject){
- let xhr = new XMLHttpRequest();
-
- xhr.open('GET', url);
- xhr.onreadystatechange = handler;
- xhr.responseType = 'json';
- xhr.setRequestHeader('Accept', 'application/json');
- xhr.send();
-
- function handler() {
- if (this.readyState === this.DONE) {
- if (this.status === 200) {
- resolve(this.response);
- } else {
- reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
- }
- }
- };
- });
- }
-
- getJSON('/posts.json').then(function(json) {
- // on fulfillment
- }, function(reason) {
- // on rejection
- });
- ```
-
- Unlike callbacks, promises are great composable primitives.
-
- ```js
- Promise.all([
- getJSON('/posts'),
- getJSON('/comments')
- ]).then(function(values){
- values[0] // => postsJSON
- values[1] // => commentsJSON
-
- return values;
- });
- ```

-
- ```js
- findUser().then(function(user){
- // user is available
- }, function(reason){
- // user is unavailable, and you are given the reason why
- });
- ```
-
- Chaining
- --------
-
- The return value of `then` is itself a promise. This second, 'downstream'
- promise is resolved with the return value of the first promise's fulfillment
- or rejection handler, or rejected if the handler throws an exception.
-
- ```js
- findUser().then(function (user) {
- return user.name;
- }, function (reason) {
- return 'default name';
- }).then(function (userName) {
- // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
- // will be `'default name'`
- });
-
- findUser().then(function (user) {
- throw new Error('Found user, but still unhappy');
- }, function (reason) {
- throw new Error('`findUser` rejected and we're unhappy');
- }).then(function (value) {
- // never reached
- }, function (reason) {
- // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
- // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
- });
- ```
- If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
-
- ```js
- findUser().then(function (user) {
- throw new PedagogicalException('Upstream error');
- }).then(function (value) {
- // never reached
- }).then(function (value) {
- // never reached
- }, function (reason) {
- // The `PedgagocialException` is propagated all the way down to here
- });
- ```
-
- Assimilation
- ------------
-
- Sometimes the value you want to propagate to a downstream promise can only be
- retrieved asynchronously. This can be achieved by returning a promise in the
- fulfillment or rejection handler. The downstream promise will then be pending
- until the returned promise is settled. This is called *assimilation*.
-
- ```js
- findUser().then(function (user) {
- return findCommentsByAuthor(user);
- }).then(function (comments) {
- // The user's comments are now available
- });
- ```
-
- If the assimliated promise rejects, then the downstream promise will also reject.
-
- ```js
- findUser().then(function (user) {
- return findCommentsByAuthor(user);
- }).then(function (comments) {
- // If `findCommentsByAuthor` fulfills, we'll have the value here
- }, function (reason) {
- // If `findCommentsByAuthor` rejects, we'll have the reason here
- });
- ```

- Simple Example
- --------------
-
- Synchronous Example
-
- ```javascript
- let result;
-
- try {
- result = findResult();
- // success
- } catch(reason) {
- // failure
- }
- ```
-
- Errback Example
-
- ```js
- findResult(function(result, err){
- if (err) {
- // failure
- } else {
- // success
- }
- });
- ```
-
- Promise Example;
-
- ```javascript
- findResult().then(function(result){
- // success
- }, function(reason){
- // failure
- });
- ```
-
- Advanced Example
- --------------
-
- Synchronous Example
-
- ```javascript
- let author, books;
-
- try {
- author = findAuthor();
- books = findBooksByAuthor(author);
- // success
- } catch(reason) {
- // failure
- }
- ```
-
- Errback Example
-
- ```js
-
- function foundBooks(books) {
-
- }
-
- function failure(reason) {
-
- }
-
- findAuthor(function(author, err){
- if (err) {
- failure(err);
- // failure
- } else {
- try {
- findBoooksByAuthor(author, function(books, err) {
- if (err) {
- failure(err);
- } else {
- try {
- foundBooks(books);
- } catch(reason) {
- failure(reason);
- }
- }
- });
- } catch(error) {
- failure(err);
- }
- // success
- }
- });
- ```
-
- Promise Example;
-
- ```javascript
- findAuthor().
- then(findBooksByAuthor).
- then(function(books){
- // found books
- }).catch(function(reason){
- // something went wrong
- });
- ```
