This was an Eat-n-Geek that I presented to the developers of my company, AllPlayers.com. In this presentation, I provide an in-depth explanation of essential patterns within JavaScript including Object Oriented Programming, Closures, the prototype, the 'this' pointer, and and other elusive JavaScript idiosyncrasies. The example within this presentation can be seen at jsfiddle.net/travistidwell/CM96a. Enjoy!
