/**
 * @file A WordPress-like hook system for JavaScript.
 *
 * This file demonstrates a simple hook system for JavaScript based on the hook
 * system in WordPress. The purpose of this is to make your code extensible and
 * allowing other developers to hook into your code with their own callbacks.
 *
 * There are other ways to do this, but this will feel right at home for
 * WordPress developers.
