jQuery is not a language, but it is a well written JavaScript code. As quoted on official jQuery website, "it is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development".
There are two simple ways to link to the jQuery library code:
Download the source code and link to it like any other JavaScript file.
Link to the Google repository of jQuery on the Google AJAX Library API servers.
