Overview of this book

RxJava is a library for composing asynchronous and event-based programs using Observable sequences for the JVM, allowing developers to build robust applications in less time. Learning RxJava addresses all the fundamentals of reactive programming to help readers write reactive code, as well as teach them an effective approach to designing and implementing reactive libraries and applications. Starting with a brief introduction to reactive programming concepts, there is an overview of Observables and Observers, the core components of RxJava, and how to combine different streams of data and events together. You will also learn simpler ways to achieve concurrency and remain highly performant, with no need for synchronization. Later on, we will leverage backpressure and other strategies to cope with rapidly-producing sources to prevent bottlenecks in your application. After covering custom operators, testing, and debugging, the book dives into hands-on examples using RxJava on Android as well as Kotlin.

Summary

This was an intense chapter, but it will provide a solid foundation as you learn how to use RxJava to tackle real-world work. RxJava, with all of its expressive power, has some nuances that are entirely due to the change of mindset it demands. It has done an impressive amount of work taking an imperative language like Java and adapting it to become reactive and functional. But this interoperability requires some understanding of the implementations between an Observable and a Observer. We touched on various ways to create Observables as well as how they interact with Observers.

Take your time trying to digest all this information but do not let it stop you from moving on to the next two chapters, where the usefulness of RxJava starts to take formation. In the next chapters, the pragmatic usefulness of RxJava will start to become clear.
