# async-each
No-bullshit, ultra-simple, 35-lines-of-code async parallel forEach function for JavaScript.
We don't need junky 30K async libs. Really.
For browsers and node.js.
## Installation
* Just include async-each before your scripts.
* `npm install async-each` if you’re using node.js.
* `bower install async-each` if you’re using [Bower](http://bower.io).
## Usage
* `each(array, iterator, callback);` — `Array`, `Function`, `(optional) Function`
* `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
* `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
Node.js:
```javascript
var each = require('async-each');
each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
if (error) console.error(error);
console.log('Contents for a, b and c:', contents);
});
```
Browser:
```javascript
window.asyncEach(list, fn, callback);
```
