History

Valerio Proietti first authored the framework and released it in September 2006 taking as his inspiration Prototype and Dean Edward's base2. MooTools originated from Moo.fx, a popular plug-in Proietti produced for Prototype in October 2005, which is still maintained and used.

Whereas Prototype extended—prototyped—many of JavaScript's native String, Array, and Function objects with additional methods, Proietti desired a framework that (at the time) further extended the native Element object as well to offer greater control of the Document Object Model (DOM).
