Table of Contents
TypeScript for Smashing People
In this chapter, we want to debunk myths. TypeScript can be so many things, and many people have different views on this programming language that has become so popular in recent years. What is TypeScript actually about? Let’s see what TypeScript has in store for us.
Working with Types
Now that we are acquainted with TypeScript and feel more comfortable using it, it’s time to dig a bit deeper into the eponymous types.
Union and Intersection Types
Starting with this chapter, we’ll go deep into TypeScript’s type system. We will learn about the set theory behind TypeScript, and how thinking in unions and intersections will help us get even more comprehensible and clearer type support.
Generics offer us a way to prepare for the unknown. They let us define types that describe a certain piece of the type system where the details are filled out later. This is the land where utility functions and utility types are born.
