jQuery is a JavaScript library created to make it easier and simpler to write JavaScript and HTML. It works on most web browsers and was invented by John Resig. The first release was in January 2006 at BarCamp NYC. Today there is a team of programmers working on jQuery, which is led by Dave Methvin.
