What is inheritance in TypeScript interfaces?

Can you explain how inheritance works in TypeScript interfaces?

Sure! In TypeScript, interfaces can extend other interfaces, allowing you to create a new interface that inherits properties from one or more existing interfaces.

Can you give me an example of that?

Of course! Here's a simple example:

interface Animal {
    name: string;
}

interface Dog extends Animal {
    breed: string;
}

const myDog: Dog = {
    name: 'Buddy',
    breed: 'Golden Retriever'
};

What happens if I want to add more properties to the Dog interface?

You can simply add more properties to the Dog interface like this:

interface Dog extends Animal {
    breed: string;
    age: number;
}

Is it possible to implement multiple interfaces in a class?

Yes, a class can implement multiple interfaces, allowing it to inherit properties from all of them. For example:

class MyDog implements Dog, AnotherInterface {
    name: string;
    breed: string;
    age: number;
}
