What are some real-world examples of interfaces in TypeScript?

Interfaces in TypeScript are used to define the structure of objects. For example, you might have an interface for a user profile that includes properties like name, age, and email.

Can you give me a specific code example?

Sure! Here's a simple example:

interface UserProfile {
    name: string;
    age: number;
    email: string;
}

const user: UserProfile = {
    name: 'Alice',
    age: 30,
    email: '[email protected]'
};

How do interfaces help in TypeScript?

Interfaces help in TypeScript by providing a way to enforce type checking, ensuring that objects adhere to a specific structure, which reduces errors.

Are there any advanced use cases for interfaces?

Yes, interfaces can extend other interfaces, allowing for more complex structures. They can also be used to define function types and callable objects.
