# Array Parallel [![Build Status](https://travis-ci.org/component/array-parallel.png)](https://travis-ci.org/component/array-parallel)

Call an array of asynchronous functions in parallel

### API

#### parallel(fns[, context[, callback]])

```js

var parallel = require('array-parallel')

parallel([

  function (done) {

    done()

  }

], this, function (err) {

})

```

#### fns

`fns` is an array of functions to call in parallel.

The argument signature should be:

```js

function (done) {

  done(new Error())

  // or

  done(null, result)

}

```

That is, each function should only take a `done` as an argument.

Each callback should only take an `Error` as the first argument,

or a value as the second.

#### context

Optional context to pass to each `fn`.

Basically `fn.call(context, done)`.

#### callback(err, results)

```js

function (err, results) {

}

```

Only argument is an `Error` argument.

It will be the first error retrieved from all the `fns`.

`results` will be an array of results from each `fn`,

thus this could be considered an asynchronous version of `[].map`.
