Part 3 : jquery

jQuery is a cross-browser JavaScript library designed to simplify the client-side scripting of HTML.[1] It was released in January 2006 at BarCamp NYC by John Resig. Used by over 31% of the 10,000 most visited websites, jQuery is the most popular JavaScript library in use today.

Part 4 : jQuery plugin

Because of jQuery's architecture, other developers can use its constructs to create plug-in code to extend its functionality. Currently there are thousands of jQuery plug-ins available on the web[11] that cover a wide range of functionality such as Ajax helpers, webservices, datagrids, dynamic lists, XML and XSLT tools, drag and drop, events, cookie handling, modal windows, even a jQuery-based Commodore 64 emulator

An important source of jQuery plug-ins is the Plugins sub-domain of the jQuery Project website. There are alternative plug-in search engines that take more specialist approaches, such as only listing plug-ins that meet certain criteria (e.g. those that have a public code repository).
