## What it is
An extensive online tutorial book teaching RxJava, the reactive programming library for the JVM, adapted from the IntroToRx guide for Rx.NET. It includes compilable example code and JUnit-based self-checking examples.

## Use cases
- learn RxJava from scratch
- understand reactive programming on the JVM
- find RxJava operator examples
- reference guide for reactive concepts
- migrate from Rx.NET to RxJava

## When to choose
- you are a Java developer new to reactive or functional programming
- you want a structured, start-to-finish RxJava tutorial
- you need a reference for specific RxJava operators

## When to avoid
- you need RxJava documentation for non-JVM languages
- you want an actively updated tutorial for the latest RxJava versions
- you need a quick cheat sheet rather than a full course

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: tutorials, programming-languages, developer-tools
- platform: jvm
- tags: reactive-programming, rxjava, tutorial, book, reactive-extensions
