JQuery

jQuery is a JavaScript library created to make it easier and simpler to write JavaScript and HTML. It works on most web browsers^[2] 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.

Today, more than 55% of the 10,000 most-visited websites use jQuery, hence it is the most popular JavaScript library being used today.^[3][4] It is free and open source software and licensed under the MIT License.^[5]

jQuery's syntax is designed to make it easier to write complicated JavaScript. Some things that are easier to do using jQuery are:

• navigate (move around) a web page
• select (choose) elements on a web page using the Document Object Model
• create animations
• handle events like user actions
• create Ajax applications.

It also allows programmers to make their own jQuery plug-ins.

Companies like Microsoft and Nokia have said that they are going to include jQuery on their mobile platforms.^[6] In addition, Microsoft is including jQuery in its Visual Studio software to use with the ASP.NET AJAX framework and ASP.NET MVC Framework.^[7] Nokia has included it in their Web Run-Time widget development platform.^[8] jQuery has also been used in MediaWiki since version 1.16.^[9]
