| 23 | * Applies the function `iteratee` to each item in `coll`, in parallel.
|
---|
| 24 | * The `iteratee` is called with an item from the list, and a callback for when
|
---|
| 25 | * it has finished. If the `iteratee` passes an error to its `callback`, the
|
---|
| 26 | * main `callback` (for the `each` function) is immediately called with the
|
---|
| 27 | * error.
|
---|
| 28 | *
|
---|
| 29 | * Note, that since this function applies `iteratee` to each item in parallel,

---|
| 30 | * there is no guarantee that the iteratee functions will complete in order.
