CHAPTER 8

Classes in TypeScript

Introduction

TypeScript has full support for JavaScript’s class system, which itself is largely a syntactic sugar on top of JavaScript’s prototypical inheritance model. TypeScript also extends JavaScript classes by adding additional features like member visibility, abstract and generic classes, and more.

We will explore all of these TypeScript features in detail over the course of this chapter; all class features of both JavaScript and TypeScript will be discussed in full, but I will draw your attention to particular features where these are TypeScript-only enhancements added on top of JavaScript’s existing functionality.

Some popular front-end development frameworks, including Google’s Angular (2+), make heavy use of TypeScript classes, so it is a good idea to become very familiar with them and how they work if you plan to use Angular or another TypeScript-based framework. By the end of this chapter, your knowledge of TypeScript classes will be in a class of its own.
