When to Become Reactive?

In Chapter 2, FRP Fundamentals, Terminology, and Basic Building Blocks, we introduced a number of concepts and called them the basic building blocks of functional reactive programming. In Chapter 3, Set up RxSwift and Convert a Basic Login App to its RxSwift Counterpart, we worked with a sample application to get a feel of RxSwift code base, and we also brushed up on some code concepts. In this chapter, we will take a step back and dive deeper into the concepts that were introduced in Chapter 2, FRP Fundamentals, Terminology, and Basic Building Blocks, and work with code to reiterate over the concepts in a different manner. We worked with a basic RxSwift application in the previous chapter and made use of Observables, subjects, and so on to get our work done without knowing the functional details of these individual concepts. Due to that, some of you might...
