Asynchronous JavaScript

Here I will dump links and key points related to asynchronous JavaScript.

RxJS

What is RxJS? RxJS is the reactive extensions library for JavaScript. It's a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. RxJS 6 is a rewrite of Reactive-Extensions/RxJS with better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface. Version 7 is currently in public beta, but is currently used by Google in production. To learn more about RxJS, please come to the conference or visit the documentation at rxjs.dev.

ReactiveX

ReactiveX is a combination of ideas from the observer and the iterator patterns and from functional programming.
