This implementation is based on [taylorhakes/promise-polyfill](https://github.com/taylorhakes/promise-polyfill) and [then/promise](https://github.com/then/promise). It has been changed to use the prototype for performance and memory reasons.

For API information about Promises, please check out this article [HTML5Rocks article](http://www.html5rocks.com/en/tutorials/es6/promises/).

## Changelog

**1.0.0**: should NOT override global promise

## Browser Support

IE8+, Chrome, Firefox, IOS 4+, Safari 5+, Opera

## Usage

```bash
$ npm install nuo --save
```

```js
import Promise from 'nuo'

new Promise((resolve, reject, notify) => {
  // resolve, reject, notify
}).then(value => {
  // do something
}).catch(error => {
  // do something
}).progress(value => {
  // do something
}).finally(() => {
  // do something
})
```

**warning: the non-standard progress and finally are NOT recommended to use, though they are working fine.**

## Testing

```bash
npm install
npm test
```
