TypeScript is a tool for JavaScript developers. It helps you build large apps. It adds static typing. Static typing finds bugs before you run your code.

Why use it?

• You find errors early.
• Your code is easier to read.
• You write faster with better tool support.
• It works with your current JavaScript files.

How it differs from JavaScript:

• JavaScript checks types at runtime.
• TypeScript checks types at compile time.
• TypeScript turns into JavaScript to run in a browser.

Who uses it?

• Large development teams.
• Enterprise companies.
• Developers using React, Angular, or Vue.

How to start:

• Install it: npm install -g typescript
• Start a project: tsc --init
• Write your code in .ts files.
• Turn it into JS: tsc filename.ts

Key parts:

• Types: Define if data is a string, number, or boolean.
• Interfaces: Define the shape of an object.
• Classes: Create blueprints for objects.
