## Installation
```.sh
npm install q-promise --save

# alternatively you can use bower (minified version by default)
bower install q-promise --save
```

## [ES6 Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
``` js
// q-promise respects the es6 promise specification
// you can use q-promise as global polyfill

if( !window.Promise ) {
  window.Promise = $q;
}
```

## Example
``` js
$q(function (resolve, reject) {
        resolve('gogogo!');
    })

    .then(function (result) {
        console.log('checkpoint 1', result);
        throw 'whoops!';
    })

    .then(function (result) {
        console.log('checkpoint 2', result);
    },function (result) {
        console.log('checkpoint 2.1', result);
        return qPromise(function (resolve, reject) {
            setTimeout(function () { resolve('all right!'); }, 400);
        });
    })

    .then(function (result) {
        console.log('checkpoint 3', result);
    }, function (reason) {
        console.log('checkpoint 3.1', reason);
    })
;
```
output:
```.sh
checkpoint 1 gogogo!
checkpoint 2.1 whoops!
# elapsed 400ms
checkpoint 3 all right!
```
