The Evolution of Async JavaScript: From Callbacks, to Promises, to Async/Await
Tyler McGinnis

Great article.

I like the evolution from callbacks to Promises and now Async/await.

However I’ve thought of an alternative path (evolution) and whether (o when) it is interesting to follow: from callbacks to Promises to Observables. That is, the reactive way (Rxjs).

I consider the reactive way a very interesting alternative, however, I know it is more difficult to master, so I wonder what do you think of this approach.
