|
---|
| 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).
