`AsyncIterator.zip([asyncIterator, syncIterable])` should presumably work (once we get [`Iterator.zip`](https://github.com/tc39/proposal-joint-iteration)).

Pomise在涉及模式中称之为**揭示构造函数**，因为生成的一个Promise的状态只会由内部函数决定，这里我们就不详细说[规范](https://segmentfault.com/a/1190000002452115)了，这次就实现一个Promise类来学习：
```javascript
function isFunction(fun) {
