Summary: Introduction to TypeScript

It was a long read, but this introduction to TypeScript was necessary to understand the logic behind many of the most brilliant parts of Angular. It gave us the chance to introduce the language syntax and explain the rationale behind its success as the syntax of choice for building the Angular framework.

We reviewed the type architecture and how we can create advanced business logic when designing functions with various alternatives for parameterized signatures. We even discovered how to bypass scope-related issues using the powerful arrow functions. We enhanced our knowledge of TypeScript by exploring some of the most common features used in Angular applications.
