In this chapter, we learned how to write custom operators. We started by writing simple operators that can perform basic tasks. Even though the operators we wrote (initially) were composable, we were not able to chain them together like standard RxCpp operators. After writing different genres of operators, we implemented chainable custom operators using the lift<T> meta operator. Finally, we saw how we can add an operator to observable<T> as well. In the next chapter, we'll delve into the world of design patterns and idioms for Rx programming. We'll start with GOF design patterns and implement different reactive programming patterns.

Overview of this book
Reactive programming is an effective way to build highly responsive applications with an easy-to-maintain code base. This book covers the essential functional reactive concepts that will help you build highly concurrent, event-driven, and asynchronous applications in a simpler and less error-prone way.
C++ Reactive Programming begins with a discussion on how event processing was undertaken by different programming systems earlier. After a brisk introduction to modern C++ (C++17), you’ll be taken through language-level concurrency and the lock-free programming model to set the stage for our foray into the Functional Programming model. Following this, you’ll be introduced to RxCpp and its programming model. You’ll be able to gain deep insights into the RxCpp library, which facilitates reactive programming. You’ll learn how to deal with reactive programming using Qt/C++ (for the desktop) and C++ microservices for the Web.
By the end of the book, you will be well versed with advanced reactive programming concepts in modern C++ (C++17).
