In this chapter, we learned what functional reactive programming is and how it compares with imperative programming. We also learned where it comes from and modeled and implemented our first functional reactive program using the
bacon.js library. We compared it with a program with and without
frp and saw how it can improve our code maintainability and testability by separating the source of the events from the actions caused by them.
In the next chapter, we will take a more in-depth look into the
bacon.js library, and what we can do with event streams, and we will also start to model and implement more complex examples using new operators.
