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. Instructions: click element headers to view specific code. Click group headers to preview all nested descriptions. CTRL+click group headers to view all nested code. Click function names to view official API docs. |
