[Filter][mdn] an array and return a [Promise][promise].

## Installation
```bash
$ npm install promise-filter
```

## Usage
```js
const filter = require('promise-filter')

Promise.resolve([1, 2, 3])
  .then(filter((val) => val >= 2))
// => [2, 3]
```

## Why?
This module is basically equivalent to [`bluebird.filter`][bluebird], but it's
handy to have the one function you need instead of a kitchen sink. Modularity!
Especially handy if you're serving to the browser and need to reduce your
javascript bundle size.

Works great in the browser with
[browserify](http://github.com/substack/node-browserify)!
