Asynchronous generators

Similar to the difference between synchronous iterators and async iterators, the main difference between a regular generator and an async generator is that an async generator yields a promise.

Async generators are a combination of async functions and generators. As a result, we can use both the await and the yield keywords inside an async generator. Calling an async generator returns an AsyncGenerator object that implements both async iterator as well as async iterable protocols. The next method of the AsyncGenerator object returns a promise.

Let us rewrite the async iterator example in the previous lesson to use an async generator:
