How do classes work in ES6?

Can you explain how classes work in ES6?

Sure! In ES6, classes are a syntactical sugar over JavaScript's existing prototype-based inheritance. They provide a clearer and more concise way to create objects and handle inheritance.

What are the main features of ES6 classes?

The main features include constructors, methods, inheritance, and static methods. You can define a class using the class keyword, and it can have a constructor for initializing objects.

How do I create a subclass in ES6?

You can create a subclass using the extends keyword. For example, class SubClass extends SuperClass {} allows SubClass to inherit properties and methods from SuperClass.

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

Absolutely! Here's a simple example:

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

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

In this example, Dog is a subclass of Animal.
