Summary

In this chapter, we walked you through the fundamentals of reactive programming and in which use cases it shines. Then, we explained the marble diagram that will be our reference for explaining RxJS operators in all the following chapters. Finally, we highlighted the use of reactive programming in Angular by illustrating concrete examples, implementations, and advantages.

Now that we have got the basics right, it is time to start preparing and explaining, in the next chapter, the application that we are going to build throughout this book, where we are going to implement all of the reactive patterns we will learn progressively.
