MooTools is a compact, modular, Object-Oriented JavaScript framework designed for the intermediate to advanced JavaScript developer. It allows you to write powerful, flexible, and cross-browser code with its elegant, well documented, and coherent API.

MooTools code respects strict standards and doesn't throw any warnings. It's well commented and has meaningful variable names: a joy to browse and a snap to understand.

Browser Compatibility

MooTools is compatible and fully tested with Safari, internet explorer 6 and 7, Firefox (and its mozilla friends), Opera and Camino.
