Screencast of writing a simple JavaScript click event handler in JSFiddle! (My first screencast.)

I've been trying to move this channel over to very developer topics but I realized that to do so I was going to have to start doing screencasts, although I didn't know the word screencast at the time. So this is my first, showing viewers how to develop a very simple JavaScript application involving the "DOMContentLoaded" event and the "click" event. The screencast takes place in the JSFiddle environment so you can do it too.
