Using the Javascript Module Pattern, and more modern JS practices, with Drupal

The JavaScript Module pattern uses immediately-invoked functional expressions (IIFE) that return objects, that include closures. This provides a way of wrapping various public and private methods and variables in a "module". This prevents them from "leaking" into the global name scope and cluttering it up or worse, colliding with other code. With this pattern only a public "API" is returned, while maintaining privacy on everything else. Additionally, I'll discuss how to split up and organize your js files for maintainability and reuse.
