What are classes in JavaScript?

Classes in JavaScript are blueprints for creating objects. They encapsulate data and behavior.

How do I create a class in JavaScript?

You can create a class using the class keyword followed by the class name and a constructor method.

Can you give me an example of a JavaScript class?

Sure! Here's a simple example:

class Dog {
    constructor(name) {
        this.name = name;
    }
    bark() {
        console.log(`${this.name} says woof!`);
    }
}

This defines a Dog class with a constructor and a method.

What is the difference between a class and a function in JavaScript?

Classes are syntactical sugar over JavaScript's existing prototype-based inheritance. Functions can be used to create objects, but classes provide a clearer structure.
