What are classes and interfaces in TypeScript?

In TypeScript, classes are blueprints for creating objects, while interfaces define contracts for those objects.

Can you give me an example of a class and an interface?

Sure! Here's a simple example:

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

class Student implements Person {
    constructor(public name: string, public age: number, public grade: number) {}
}

How do I implement multiple interfaces in a class?

You can implement multiple interfaces by separating them with commas in the class declaration. For example:

interface Employee {
    id: number;
}

interface Person {
    name: string;
}

class Manager implements Employee, Person {
    constructor(public id: number, public name: string) {}
}

What are the benefits of using interfaces?

Interfaces provide a way to define the structure of an object, ensuring type safety and enabling better code organization.
