Finally, all principles have now been covered, as well as the tools needed to implement functional and reactive code. By the way, the previous example is already a functional application: component_a, is a pure function, and component_b is a side effect. However, the main code that instantiates and connects both components cannot be a pure function because it uses component_b which is a side effect. If the instantiation of this side effect is moved to a dedicated side effect initialization part of the code then the rest of the code would be completely composed of pure functions. This is the concept of the Cycle.js framework, a JavaScript framework that allows for writing functional and reactive code. These principles have been used by other frameworks since its creation, and they are applicable to Python and RxPY. With just a few changes...

Overview of this book
Reactive programming is central to many concurrent systems, but it’s famous for its steep learning curve, which makes most developers feel like they're hitting a wall. With this book, you will get to grips with reactive programming by steadily exploring various concepts
This hands-on guide gets you started with Reactive Programming (RP) in Python. You will learn abouta the principles and benefits of using RP, which can be leveraged to build powerful concurrent applications. As you progress through the chapters, you will be introduced to the paradigm of Functional and Reactive Programming (FaRP), observables and observers, and concurrency and parallelism. The book will then take you through the implementation of an audio transcoding server and introduce you to a library that helps in the writing of FaRP code. You will understand how to use third-party services and dynamically reconfigure an application.
By the end of the book, you will also have learned how to deploy and scale your applications with Docker and Traefik and explore the significant potential behind the reactive streams concept, and you'll have got to grips with a comprehensive set of best practices.
