Summary: Observables and RxJS

We have covered a lot in this chapter. It has been one of the largest in this course, but it is worth understanding all that we have covered in this chapter in order to be able to write fast and powerful Angular applications.

The use of Observables and RxJs is an extremely important part of how we build applications with Angular. With the need for modern web applications to be extremely fast and responsive to end-user demands, being able to design and build applications that make use of Observables means that we can create Angular applications that react to the user’s needs.
