});

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>;

const mix1 = Ember.Mixin.create({
    foo: 1,
});

const mix2 = Ember.Mixin.create({
    bar: 2,
});

const component1 = Ember.Component.extend(mix1, mix2, {
    lyft: Ember.inject.service(),
    cars: Ember.computed.readOnly('lyft.cars'),
});
