Overview

Handling asynchronous information is a common task in our everyday lives as developers. Reactive programming is a programming paradigm that helps us consume, digest, and transform asynchronous information using data streams. RxJS is a JavaScript library that provides methods to manipulate data streams using observables.

Angular provides an unparalleled toolset to help us when it comes to working with asynchronous data. Observable streams are at the forefront of this toolset, giving developers a rich set of capabilities when creating Angular applications. The core of the Angular framework is lightly dependent on RxJS. Other Angular packages, such as the router and the HTTP client, are more tightly coupled with observables.
