TypeScript is a version of JavaScript. It adds a type system to your code.

JavaScript finds errors when you run the app. TypeScript finds errors while you write the code. If you use a string instead of a number, your editor shows the error.

This helps you avoid bugs. It makes changing code safer.

Why use TypeScript?

• Code stays documented.
• Your editor suggests the right code.
• Large projects stay easy to manage.
• You add it to existing projects one file at a time.

Types disappear after you compile the code. They only exist to help you build the app.

Key tools:

• Basic types: Define variables as strings, numbers, or booleans.
• Interfaces: Create a contract for object structures.
• Generics: Write code for any type without losing safety.
• Enums: Define a set of fixed values.
• Union types: Let a variable be one of several types.
