26 | * Applies the function `iteratee` to each item in `coll`, in parallel.
|
27 | * The `iteratee` is called with an item from the list, and a callback for when
|
28 | * it has finished. If the `iteratee` passes an error to its `callback`, the
|
29 | * main `callback` (for the `each` function) is immediately called with the
|
30 | * error.
|
31 | *
|
32 | * Note, that since this function applies `iteratee` to each item in parallel,
|
33 | * there is no guarantee that the iteratee functions will complete in order.

41 | * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
|
42 | * @param {AsyncFunction} iteratee - An async function to apply to
|
43 | * each item in `coll`. Invoked with (item, callback).
|
44 | * The array index is not passed to the iteratee.
|
45 | * If you need the index, use `eachOf`.
|
46 | * @param {Function} [callback] - A callback which is called when all
|
47 | * `iteratee` functions have finished, or an error occurs. Invoked with (err).
