JQuery

JQuery is a fast and simple, lightweight JavaScript library that works across all current major browsers. It is currently the most popular Javascript library. Its main functionality is to reduce the complexity of traversing the Document element (Webpage). In so doing Jquery allows a developer to quickly find the element, manipulate it as needed without adding too much overhead to the end user’s load time.

Client validation, cool animations that work on mobile devices as well as web (sliders, carousels, flyovers, text manipulations,etc), security checks, lazy load ajax data retrievals are just some of the examples of what Jquery can do.
