Lesson 5: Understand Class Inheritance in JavaScript

Lesson 5: Understand Class Inheritance in JavaScript Technologies: JavaScript Lesson Description To cut down the amount of code you need to write, take advantage of class inheritance in JavaScript. Use the extends keyword to inherit all functionality from an existing class, then add your own properties and methods to extend the functionality. Override a base class' method by providing a method with the same name in the extended class. This overridden method can add to, or completely replace the original method. You may also extend any built-in JavaScript class and add your own functionality.
