}, (result) => {
return { name: 'i am pure function' };
}, (result) => {
return fetchUrl('defer2.json');
}).then((result) => {
// do something
});
```
### `$.parallel(...deferreds)`
Run deferreds collection of functions in parallel, and return a promise that is fulfilled when all the items in the array are fulfilled

}, fetchUrl('defer2.json'), ['one', 'two']).then((v1, v2, v3) => {
...
});
```
### `$.promisify(value)`
Return a promise that will wrap the given value
