Class Inheritance in JavaScript

In JavaScript, class inheritance is a mechanism that allows one class referred to as the "child" class (or "subclass") to inherit properties and methods from another class referred to as the "parent" class (or "superclass").

It enables code reuse and allows developers to create a hierarchy of classes that share common functionality, while allowing each subclass to have its own specialized behaviors.

Create a child class

To create a class that inherits the fields and methods from another class, you can use the extends keyword:

class ParentClass {  //}class ChildClass extends ParentClass {  //}

The super keyword

The super keyword enables the child class to access the properties and methods defined in the parent class.

When used within the child's constructor, the super() method allows the child to invoke the parent constructor to ensure that its properties are correctly initialized.

class ParentClass {  constructor(...parameters?) {    // ...  }
