Lesson 6: Implement Static Properties and Methods in JavaScript
Technologies: JavaScript

Lesson Description
To hold onto a piece of data for all instances of a class, use the static keyword in JavaScript. This data, exposed as a static property, is accessed only through the class name and not the instance variable. You can create private or public static properties and methods. Static methods are generally used when you pass some data in and something is returned with no need to hold onto state. A static constructor is used to initialize your static properties. In this lesson you create several classes to illustrate the use of static.
