import {

} from '../-internal';
/**
`Promise.reject` returns a promise rejected with the passed `reason`.
It is shorthand for the following:
```javascript
let promise = new Promise(function(resolve, reject){
reject(new Error('WHOOPS'));
});
promise.then(function(value){
// Code here doesn't run because the promise is rejected!
}, function(reason){
// reason.message === 'WHOOPS'
});
```
Instead of writing the above, your code now simply becomes the following:
```javascript
let promise = Promise.reject(new Error('WHOOPS'));
promise.then(function(value){
// Code here doesn't run because the promise is rejected!
}, function(reason){
// reason.message === 'WHOOPS'
});
```
@method reject
@static
@param {Any} reason value that the returned promise will be rejected with.
Useful for tooling.
@return {Promise} a promise rejected with the given `reason`.
*/
export default function reject(reason) {
/*jshint validthis:true */
let Constructor = this;
let promise = new Constructor(noop);
_reject(promise, reason);
return promise;
}
