TypeScript
Add real type safety to the JavaScript you already know: build a pizza ordering app, a typed Express API, and a React to-do app with drag-and-drop, then ship a full-stack MERN app with TypeScript, authentication, and deployment.
Learn why TypeScript exists, then go through its full type system: interfaces, classes, and generics.
- What TypeScript adds on top of JavaScript
- Why static typing catches bugs before runtime
- How the TypeScript compiler fits into a project
- Type inference, unions, and type aliases
- Interfaces, and when to use them over types
- Classes with access modifiers, getters, and setters
- Generics in functions, classes, and arrays
- Type narrowing and discriminated unions
