What are interfaces and types in TypeScript?

Can you explain the difference between interfaces and types in TypeScript?

Sure! In TypeScript, both interfaces and types can be used to define the shape of an object, but they have some differences. Interfaces are primarily used for defining object structures and can be extended or implemented, while types can represent any valid TypeScript type, including primitives, unions, and intersections.

Can you give me an example of an interface?

Absolutely! Here's a simple example of an interface:

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

What about a type example?

Here's an example of a type alias:

type Point = {
  x: number;
  y: number;
};

When should I use an interface over a type?

Use interfaces when you want to define a contract for classes or when you need to extend existing structures. Use types for more complex types like unions or when you want to create a type alias for primitives.
