MooTools provides the user with a number of advantages over native JavaScript. These include:

► An extensible and modular framework allowing developers to choose their own customized combination of components.

► MooTools follows object-oriented practices and the DRY principle.

► An advanced effects component, with optimized transitions such as easing equations used by many Flash developers.

► Enhancements to the DOM, enabling developers to easily add, modify, select, and delete DOM elements. Storing and retrieving information with Element storage is also supported.
