What are TypeScript interfaces and classes?

Can you explain what TypeScript interfaces are?

TypeScript interfaces are a way to define the structure of an object. They allow you to specify the properties and their types that an object should have.

How do interfaces differ from classes in TypeScript?

Interfaces define a contract for objects, while classes are blueprints for creating objects. Classes can implement interfaces.

Can you give me an example of using an interface in TypeScript?

Sure! Here's a simple example:

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

const john: Person = { name: 'John', age: 30 };

What about classes? How do I create one?

You can create a class in TypeScript like this:

class Animal {
    constructor(public name: string) {}
    speak() {
        console.log(`${this.name} makes a noise.`);
    }
}

const dog = new Animal('Dog');
dog.speak(); // Dog makes a noise.
