Mastering TypeScript Types for Better Code Safety

Introduction

TypeScript types are the backbone of writing predictable and maintainable code. By explicitly defining the kind of data your application works with, you reduce bugs and make your code easier to understand.

Types allow you to specify what kind of values a variable can hold:

let username: string = "Vivek";
let age: number = 21;
let isActive: boolean = true;
