+
+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 the Node.js environment. If you use Async with webpack, install [`async-es`](https://www.npmjs.com/package/async-es) instead.
+
+For Documentation, visit <https://caolan.github.io/async/>

+*For Async v1.5.x documentation, go [HERE](https://github.com/caolan/async/blob/v1.5.2/README.md)*

+
+async.forEachOf(obj, (value, key, callback) => {

+ *
+ * If any of the {@link AsyncFunction}s pass an error to their callback, the `auto` sequence
+ * will stop. Further tasks will not execute (so any other functions depending

+ * error.
+ *
+ * {@link AsyncFunction}s also receive an object containing the results of functions which
+ * have completed so far as the first argument, if they have dependencies. If a
+ * task function has no dependencies, it will only be passed a callback.
+ *
+ * @name auto
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @category Control Flow
+ * @param {Object} tasks - An object. Each of its properties is either a

+ * in the array. The object's key of a property serves as the name of the task
+ * defined by that property, i.e. can be used when specifying requirements for
+ * other tasks. The function receives one or two arguments:
+ * * a `results` object, containing the results of the previously executed
+ *   functions, only passed if the task has any dependencies,
+ * * a `callback(err, result)` function, which must be called when finished,
+ *   passing an `error` (which can be `null`) and the result of the function's
+ *   execution.
+ * @param {number} [concurrency=Infinity] - An optional `integer` for
+ * determining the maximum number of tasks that can be run in parallel. By
+ * default, as many as possible.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback. Results are always returned; however, if an
+ * error occurs, no further `tasks` will be performed, and the results object
+ * will only contain partial results. Invoked with (err, results).

+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');

+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});

+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
