jQuery:

jQuery is a JavaScript library that was initially released in 2006 and is currently used by more than 55% of the 10,000 most visited websites. It is claimed to be the most popular JavaScript library today. The Joomla! Project has decided to include jQuery in the core of Joomla 3.0 and on.

While the MooTools JavaScript library will still be included in the Joomla core as well, jQuery will be heavily used as it integrates directly with the Twitter Bootstrap framework, which the Joomla CMS is based on beginning with version 3.0.

MooTools:

MooTools is an object-oriented JavaScript framework that is still somewhat widely used throughout the internet. It is the JavaScript library that Joomla has used since its inception. The name is taken from an acronym: My Object-Oriented Tools.

Using a JavaScript library such as MooTools allows developers to rapidly create extensions and update code, while reusing trustworthy pieces of code over and over. This saves time and is generally thought to greatly reduce errors and security problems.
