Overview

Learn about the content that will be covered in this chapter.

Previously, we learned that the code of an Angular project is written in TypeScript. 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 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.
