20. new Operator & Constructors
Anjana introduces classes in JavaScript and compares the syntax to other object-oriented languages. In JavaScript, the class keyword is a syntactic convenience and doesn't fundamentally change the object's behavior under the hood. Class constructors are also introduced in this lesson.

22. Class Inheritance
Anjana explains how to extend a class to create a subclass. The subclass inherits the properties and methods of the parent class. The super() method allows the subclass to call the parent class's constructor to run any initialization code.

Anjana debugs and has an issue with the Dark Modal where the selected theme is not saved when the Modal is closed. This is due to the form refreshing the page on submission. The preventDefault method will prevent the refresh from happening.

28. Introduction to Node.js
Anjana introduces Node.js as a way to run JavaScript outside of the browser. Developers can write JavaScript that runs server-side or in the command line. While some APIs are similar, Node-based applications can access system-level resources and other APIs not available in the browser. The Node.js REPL (Read-Evaluate-Print Loop) is also demonstrated in this lesson.
