What are the benefits of using interfaces in TypeScript?

Using interfaces in TypeScript helps define contracts for objects, ensuring type safety and better code organization.

Can you give me an example of how to use an interface?

Sure! Here's a simple example:

interface User {
  name: string;
  age: number;
}

const user: User = {
  name: 'Alice',
  age: 30
};

What happens if I don't use interfaces?

Without interfaces, you might encounter type errors at runtime, making your code less reliable and harder to maintain.

Are there any performance implications of using interfaces?

No, interfaces are a compile-time construct in TypeScript, so they don't affect runtime performance.
