Managing TypeScript Types

Master TypeScript's type system for type-safe, maintainable, and self-documenting code.

Quick Start

Basic Types

// Primitives
const name: string = 'John';
const age: number = 30;
const isActive: boolean = true;
const nothing: null = null;
const notDefined: undefined = undefined;

// Arrays
const numbers: number[] = [1, 2, 3];
const strings: Array<string> = ['a', 'b', 'c'];
