08/10/22 • 47 min
RxJS (Reactive Extensions for JavaScript) is a complex and very interesting topic. The Rx (Reactive Extensions), originating from Microsoft, has been around for a very long time migrating from one platform to another. These days every programming language has its own native implementation of Rx. This episode is fully dedicated to RxJS.
In this episode we are discussing:
- What is RxJS and what problem does it solve?
- Ben’s personal story with RxJS and how it all started
- A quick history or RxJS
- What companies are using RxJS and how does it help them?
- RxJS and Angular (RxJS on Google scale)
- Reactive Programming and how RxJS related to that.
- RxJS vs another Reactive Programming libraries (BaconJS, KefirJS, etc)
- Observable vs promise
- When to use observables, when to use promise
- Tips and tricks for newcomers
- What is the future of RxJS
- Observable TC39 proposal
- Observables as a part of ECMAScript standard

Reactive Angular
There is a lot of buzz around reactivity and reactive programming these days.
All reactive Angular API is built on top of RxJS library so there is a lot of reactivity built-in within Angular.
What do you think, should Angular have First-class RxJS support, should it be optional or may be Angular should support both options?
Lets discuss 👉 Twitter thread
