JS Libs Deconstructed

The Deconstructed series is designed to visually and interactively deconstruct the internal code of JavaScript libraries, including jQuery, Prototype and MooTools.

It breaks the physical JavaScript into visual blocks that you can easiliy navigate. Each block opens to reveal its internal code. Clickable hyperlinks allow you to follow program flow.

Great resource to study and learn different JavaScript libraries!
