                    In this part
- In this last part of the book, you’ll take a deep dive into complex example apps built with RxJava and the architectures you’ve learned.
 - Chapters 11 and 12 show how to create a real-time chat application using the WebSocket Protocol (usually called just WebSockets). You’ll learn about a suitable place to attach handlers for incoming messages as well as how to keep the state of the app up-to-date.
 - Chapter 13 focuses on a special case of containing animation state in the view model and transitioning between different incoming values.
 - Finally, chapter 14 explains the internal workings of a fully functioning maps client. You’ll see how to model complex view outputs into a reactive system.
