Introduction

Inheritance is a fundamental concept in object-oriented programming that allows one class to inherit properties and methods from another class. In JavaScript, you can achieve inheritance using the extends keyword and the super function. This guide explains how to inherit from a class in JavaScript.

Creating a Base Class

First, let's define a base class called Vehicle.

Inheriting from a Class

To create a derived class that inherits from the Vehicle class, use the extends keyword. The derived class can also have its own properties and methods.

Creating an Object from the Derived Class

You can create instances of the derived class just like you would with the base class.

Example of Object Creation

Creating Another Object

Conclusion

Inheriting from a class in JavaScript is straightforward using the extends keyword along with the super function to access the parent class's constructor. This approach promotes code reuse and helps organize related classes effectively.
