JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

Javascript modules are a great way to isolate your code, but they are not very re-usable.  If we implement the factory pattern inside of one of our modules we get code re-use without losing the encapsulation benefits of a javascript module.

The Factory Pattern for Javascript Modules

The and (&&) and or (||) operators in javascript do not function like traditional logical operators.  We can use them to our advantage to eliminate some boilerplate code when writing conditional expressions.

Double && (and) Double || (or) = Double Functionality

Javascript modules are a design pattern that allow you to encapsulate your code into smaller self managing pieces.  They help you separate your code, protect your variables, and provide an easy way to expose only the parts of your component that you want to be exposed.
