Introduction

JavaScript, starting from ECMAScript 2015 (ES6), supports classes as a syntactical sugar over its existing prototype-based inheritance. Classes provide a clear structure for creating objects and are a more intuitive way to work with object-oriented programming in JavaScript.

Creating a Class

Basic Class Declaration

To create a class in JavaScript, you use the class keyword followed by the class name and a block containing methods and a constructor.

Instantiating a Class

You can create an instance of a class using the new keyword.

Class Inheritance

Classes in JavaScript can also extend other classes, allowing for inheritance.

Example of Inheritance

Conclusion

Creating a class in JavaScript is straightforward with the class keyword. You can define properties and methods within the class and utilize inheritance for better code organization and reusability. This enhances your ability to implement object-oriented programming patterns effectively in JavaScript.
