Joomla 3.x now ships with jQuery in the core because bootstrap was designed to work with it and the goal is to get all of main core functions working over on jquery. It also ships with mootools for compatibility reasons.

3rd party extensions

In order to load the Joomla jQuery library from a 3rd party extension, the extension simply has to call the JHtml-class: JHtml::_(‘jquery.framework’);.
