When should I use interfaces in TypeScript?

You should use interfaces in TypeScript when you want to define the shape of an object, especially for complex data structures.

Can you give me an example of an interface?

Sure! Here's a simple example:

interface User {
  id: number;
  name: string;
  email: string;
}

What are the benefits of using interfaces over types?

Interfaces are extendable and can be merged, making them more flexible for defining object shapes, especially in large applications.

Are there any situations where I shouldn't use interfaces?

Yes, if you need a union type or a more complex type definition, using type might be more appropriate than an interface.
