What is RxJS?
To quote the official documentation:
RxJS (or reactive extensions for javascript) is a library for composing asynchronous and event-based programs by using observable sequences
One of the best things about RxJS is readability. You can mix asynchronous and synchronous logic, as well as use hundreds of out-of-the-box operators that are also well documented and tested, allowing you to do all sorts of asynchronous operations super quickly. There are also debugging tools available to debug and improve on your observable piping.
Other cool features include:
✍ The ability to be cancellable,
🚩 The error handling is quite neat ,
⚡ The power to listen to the result of an observable in multiple places.
