In this chapter, you created a client-server application. You used NodeJS to create a server, with MongoDB and Phaethon. You also learned more about asynchronous programming and the structural type system. We used our knowledge of Angular from the first chapter to create the client side.
In the next chapter, we will create another client-server application. That application is not a CRUD application, but a real-time chat application. We will be using React instead of Angular.
