Hello Friends,

JQuery is the most popular JavaScript library in use today.jQuery is free, open source software, dual-licensed under the MIT License and the GNU General Public License, Version 2.jQuery’s syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plugins on top of the JavaScript library. Providing this option, developers are able to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets.
