What is the difference between an interface and a class in TypeScript?

In TypeScript, an interface defines a contract for objects, while a class is a blueprint for creating objects with properties and methods.

Can you give me an example of each?

Sure! An interface might look like this: interface Person { name: string; age: number; }. A class could be: class Employee implements Person { constructor(public name: string, public age: number) {} }.

When should I use an interface instead of a class?

Use an interface when you want to define a shape for objects without implementing behavior. Use a class when you need to create instances with methods and properties.

Can interfaces extend other interfaces?

Yes, interfaces can extend other interfaces, allowing you to create complex types by combining multiple interfaces.
