JavaScript, the programming language of the web, has evolved significantly over the years. One of the most notable additions to its syntax is the introduction of classes, which streamline object-oriented programming (OOP) in JavaScript. If you’re new to classes or looking to refresh your understanding, you’re in the right place.

In this article, we’ll break down the basics of classes in JavaScript with straightforward examples.

Understanding Classes in JavaScript

Before classes were introduced in JavaScript, developers relied on constructor functions and prototypes to create objects and implement inheritance. While this approach worked, it often led to verbose and less intuitive code. Classes offer a more structured and familiar syntax for working with objects and inheritance.

Creating a Class

To define a class in JavaScript, you use the class keyword followed by the class name. Here's a simple example:

class Rectangle {
  constructor(width, height) {
    this.width = width;
