[async.mapLimit](https://github.com/caolan/async#maplimitarr-limit-iterator-callback)'s
|
||
|
|
functionality available as a standalone npm module.
|
||
|
|
|
||
|
|
I often find myself pulling in [async](http://github.com/caolan/async) for this
|
||
|
|
method alone, so in the spirit of breaking things into smaller pieces here's
|
||
|
|
that method as a single thing you can require.
|
||
|
|
|
||
|
|
## Usage ##

### `mapLimit(arr, limit, iterator, callback)` ###
|
||
|
|
|
||
|
|
The same as map only no more than "limit" iterators will be simultaneously
|
||
|
|
running at any time.
|
||
|
|
|
||
|
|
Note that the items are not processed in batches, so there is no guarantee
|
||
|
|
that the first "limit" iterator functions will complete before any others are
|
||
|
|
started.
|
||
|
|
|
||
|
|
#### Arguments ####
|
||
|
|
|
||
|
|
* **arr** - An array to iterate over.
|
||
|
|
* **limit** - The maximum number of iterators to run at any time.
|
||
|
|
* **iterator(item, callback)** - A function to apply to each item in the array. The iterator is passed a callback(err, transformed) which must be called once it has completed with an error (which can be null) and a transformed item.
|
||
|
|
* **callback(err, results)** - A callback which is called after all the iterator functions have finished, or an error has occurred. Results is an array of the transformed items from the original array.
