RxJava

RxJava is a Java implementation of ReactiveX, a library for composing asynchronous and event-based programs using observable sequences. It provides a powerful way to handle asynchronous data streams and events in a declarative, functional style, making it easier to manage complex concurrency and data flow in applications.

Also known as: Reactive Extensions for Java, RxJava2, RxJava3, ReactiveX Java, Rx

Why learn RxJava?

Developers should learn RxJava when building Android apps or Java-based backend services that require efficient handling of asynchronous operations, such as network calls, user input events, or database queries. It's particularly useful for managing complex data transformations, error handling, and thread management in a clean, maintainable way, reducing callback hell and improving code readability.
