How do I structure a class in TypeScript?

How do I structure a class in TypeScript?

In TypeScript, you can structure a class using the class keyword, followed by the class name. You can define properties and methods within the class.

Can you give me an example of a simple class?

Sure! Here's a basic example:

class Animal {
    name: string;

    constructor(name: string) {
        this.name = name;
    }

    speak() {
        console.log(`${this.name} makes a noise.`);
    }
}

This defines an Animal class with a constructor and a method.

What about inheritance in TypeScript classes?

Inheritance in TypeScript allows you to create a new class based on an existing class. You can use the extends keyword. For example:

class Dog extends Animal {
    speak() {
        console.log(`${this.name} barks.`);
    }
}

How do I implement interfaces with classes?

You can implement interfaces in TypeScript classes using the implements keyword. For example:

interface Pet {
    name: string;
    speak(): void;
}

class Cat implements Pet {
    constructor(public name: string) {}
    speak() {
        console.log(`${this.name} meows.`);
    }
}
