|
||
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)

|
||
39 | * @param {Array|Iterable|Object} coll - A collection to iterate over.
|
||
40 | * @param {Function} iteratee - A function to apply to each item in `coll`.
|
||
41 | * The iteratee is passed a `callback(err, transformed)` which must be called
|
||
42 | * once it has completed with an error (which can be `null`) and a
|
||
43 | * transformed item. Invoked with (item, callback).
|
||
44 | * @param {Function} [callback] - A callback which is called when all `iteratee`
|
||
45 | * functions have finished, or an error occurs. Results is an Array of the
|
||
46 | * transformed items from the `coll`. Invoked with (err, results).
|
||
47 | * @example
|
||
48 | *
|
||
49 | * async.map(['file1','file2','file3'], fs.stat, function(err, results) {
|
||
50 | * // results is now an array of stats for each file
|

51 | * });
