TypeScript Basics for JavaScript Developers

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

Why TypeScript?

TypeScript adds static type checking to JavaScript, helping you catch errors early and write more maintainable code.

Basic Types

let name: string = "John";
let age: number = 30;
let isActive: boolean = true;

Benefits

• Type safety
• Better IDE support
• Improved code documentation
• Easier refactoring

TypeScript makes JavaScript development more robust and scalable.
