TypeScript is a typed superset of JavaScript that compiles to plain JavaScript and adds optional static typing, interfaces, and modern language features.

What are TypeScript interfaces?

Interfaces in TypeScript define the shape of objects and provide contracts for classes, enabling better type checking and code clarity.

What are generics in TypeScript?

Generics allow you to create reusable components that work with a variety of types while preserving type information, making your code more flexible and type-safe.
