+
+
+Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install --save async`, it can also be used directly in the browser.
+
+This version of the package is optimized for building with webpack. If you use Async in Node.js, install [`async`](https://www.npmjs.com/package/async) instead.

+```javascript
+// for use with callbacks...
+import { forEachOf } from "async-es";
+
+const images = {cat: "/cat.png", dog: "/dog.png", duck: "/duck.png"};
+const sizes = {};
+
+forEachOf(images, (value, key, callback) => {
+ const imageElem = new Image();
+ imageElem.src = value;
+ imageElem.addEventListener("load", () => {
+ sizes[key] = {
+ width: imageElem.naturalWidth,
+ height: imageElem.naturalHeight,
+ };
+ callback();
+ });
+ imageElem.addEventListener("error", (e) => {
+ callback(e);
+ });
+}, err => {
+ if (err) console.error(err.message);
+ // `sizes` is now a map of image sizes
+ doSomethingWith(sizes);
+});
+```
+
+```javascript
+import { mapLimit } from "async-es";
+
+// ...or ES2017 async functions
+mapLimit(urls, 5, async function(url) {
+ const response = await fetch(url)
+ return response.body
+}, (err, results) => {
+ if (err) throw err
+ // results is now an array of the response bodies
+ console.log(results)
