Summary

In this chapter, we started on our second application and made a lot of strides in implementing the feature set. You learned about TypeScript modules and generics. Then, we started creating our application and implemented most of the core functionalities using Angular features, such as components, services, multiple component communication, and life cycle hooks.

In the next chapter, we will make changes to our application to fetch data from HTTP. You will learn about TypeScript features, which helps us make web service calls.
