Understanding TypeScript

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It adds optional static type definitions to JavaScript, enabling better tooling and catching errors at compile time.

Why Use TypeScript?

• Type Safety: Catch errors during development
• Better IDE Support: Enhanced autocomplete and refactoring
• Improved Code Quality: Self-documenting code with types
• Easy Migration: Gradual adoption from JavaScript

Basic Types

TypeScript provides several basic types:

let isDone: boolean = false;
let decimal: number = 6;
let color: string = "blue";
let list: number[] = [1, 2, 3];

Interfaces

Interfaces define the shape of objects:

interface User {
  name: string;
  age: number;
  email?: string; // Optional property
}

TypeScript makes JavaScript development more robust and maintainable.
