* Applies `iteratee` to each item in `coll`, concatenating the results. Returns

* the concatenated list. The `iteratee`s are called in parallel, and the
|
|
* results are concatenated as they return. The results array will be returned in
|
|
* the original order of `coll` passed to the `iteratee` function.

* @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
|
|
* @param {AsyncFunction} iteratee - A function to apply to each item in `coll`,
|
|
* which should use an array as its result. Invoked with (item, callback).
|
|
* @param {Function} [callback] - A callback which is called after all the
|
|
* `iteratee` functions have finished, or an error occurs. Results is an array
|
|
* containing the concatenated results of the `iteratee` function. Invoked with
|
|
* (err, results).
|
|
* @returns A Promise, if no callback is passed
|
|
* @example
|
|
*
|
|
* async.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files) {
|
|
* // files is now a list of filenames that exist in the 3 directories
