What are ES6 classes and how do they work?

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

Can you explain the difference between a class and a constructor function?

Sure! A class is a blueprint for creating objects, while a constructor function is a traditional way to create objects in JavaScript. Classes use the class keyword and can include methods, while constructor functions are regular functions.

What are some key features of ES6 classes?

Key features include inheritance using the extends keyword, the ability to define methods, and the use of the super keyword to call parent class methods.

How do I create an instance of a class?

You can create an instance of a class using the new keyword followed by the class name, like this: const instance = new MyClass();.

Can you give me an example of inheritance in ES6 classes?
