Writing in TypeScript and leveraging its static typing gives us a remarkable advantage over other scripting languages. This chapter is not a thorough overview of the TypeScript language. Instead, we'll just focus on the core elements and study them in detail on our journey through Angular. The good news is that TypeScript is not all that complex, and we will manage to cover most of its relevant parts.

In this chapter, we will cover the following topics:

  • Look at the background and rationale behind TypeScript
  • Discover online resources to practice with while we learn
  • Recap on the concept of typed values and their representation
  • Build our custom types, based on classes and interfaces
  • Emphasize the use of advanced types in an Angular project
  • Learn to organize our application...
