I've been experimenting with codepen a lot lately. There is something so cool about experimenting with some tricky javascript and sending a link to a code sandbox somewhere to someone and they fork it and say, "here's the fix".

Drupal 7 includes jQuery 1.4.4 by default. So getting started using jQuery in your module or theme is really simple. The easiest way to include a javascript file is to include it in a .info file with a line like "scripts[]= myfile.js".
