示例1: resolve
resolve('ok!');
// on failure
reject('no-k!');
});
promise.then(
(value: any) => {
// on fulfillment
},
(reason: any) => {
// on rejection
}
);
// make sure Ember.RSVP.Promise can be reference as a type
declare function promiseReturningFunction(urn: string): Ember.RSVP.Promise<string>;
