/**
|
18
|
* Produces a new collection of values by mapping each value in `coll` through
|
19
|
* the `iteratee` function. The `iteratee` is called with an item from `coll`
|
20
|
* and a callback for when it has finished processing. Each of these callback
|
21
|
* takes 2 arguments: an `error`, and the transformed item from `coll`. If
|
22
|
* `iteratee` passes an error to its callback, the main `callback` (for the
|
23
|
* `map` function) is immediately called with the error.
|
24
|
*
|
25
|
* Note, that since this function applies the `iteratee` to each item in
|
26
|
* parallel, there is no guarantee that the `iteratee` functions will complete
|
27
|
* in order. However, the results array will be in the same order as the
|
28
|
* original `coll`.
|
29
|
*
|
30
|
* If `map` is passed an Object, the results will be an Array. The results
|
31
|
* will roughly be in the order of the original Objects' keys (but this can
|
32
|
* vary across JavaScript engines).

46
|
* transformed items from the `coll`. Invoked with (err, results).
