1.jQuery is a multi-browser JavaScript library designed to simplify the client-side scripting of HTML. It was released in January 2006 at BarCamp NYC by John Resig. It is currently developed by a team of developers led by Dave Methvin. Used by over 65% of the 10,000 most visited websites, jQuery is the most popular JavaScript library in use today.
