Class Inheritance

Inheritance in JavaScript

Usually, classes are used for inheritance in object-oriented programming. Here is a brief refresher on inheritance; inheritance enables new classes to take on the properties and methods of existing classes. A class that another class inherits is called a superclass or base class. A class that inherits from a superclass is called a subclass or derived class. In JavaScript, the extends keyword can be used to inherit one class from another class as shown in the following example. So, the derived class, ReactDeveloper, inherits all the abilities from the base class, Developer, and also adds its specialized capabilities, namely the getJob() method to it.
