/**

|
|
* Returns a new object, where each value corresponds to an array of items, from
|
||
|
|
* `coll`, that returned the corresponding key. That is, the keys of the object
|
||
|
|
* correspond to the values passed to the `iteratee` callback.
|
||
|
|
*
|
||
|
|
* Note: Since this function applies the `iteratee` to each item in parallel,
|
||
|
|
* there is no guarantee that the `iteratee` functions will complete in order.
|
||
|
|
* However, the values for each key in the `result` will be in the same order as
|
||
|
|
* the original `coll`. For Objects, the values will roughly be in the order of
|
||
|
|
* the original Objects' keys (but this can vary across JavaScript engines).

* @param {Array|Iterable|Object} coll - A collection to iterate over.

|
|
* @param {AsyncFunction} iteratee - An async function to apply to each item in
|
||
|
|
* `coll`.
|
||
|
|
* The iteratee should complete with a `key` to group the value under.
|
||
|
|
* Invoked with (value, callback).
|
||
|
|
* @param {Function} [callback] - A callback which is called when all `iteratee`
|
||
|
|
* functions have finished, or an error occurs. Result is an `Object` whoses
|
||
|
|
* properties are arrays of values which returned the corresponding key.

* }, function(err, result) {
