/**
`RSVP.defer` returns an object similar to jQuery's `$.Deferred`.
`RSVP.defer` should be used when porting over code reliant on `$.Deferred`'s
interface. New code should use the `RSVP.Promise` constructor instead.
The object returned from `RSVP.defer` is a plain object with three properties:
* promise - an `RSVP.Promise`.
* reject - a function that causes the `promise` property on this object to
become rejected
* resolve - a function that causes the `promise` property on this object to
become fulfilled.
Example:
```javascript
var deferred = RSVP.defer();
deferred.resolve("Success!");
defered.promise.then(function(value){
// value here is "Success!"
});
```
@method defer
@static
@for RSVP
@param {String} label optional string for labeling the promise.
Useful for tooling.
@return {Object}
*/
export default function defer(label) {
var deferred = { };
deferred.promise = new Promise(function(resolve, reject) {
deferred.resolve = resolve;
deferred.reject = reject;
}, label);
return deferred;
}
