jQuery is library, which functions on many browsers and is compatible with CSS3. Its main goal is to speed up and simplify programming scripting during website development. jQuery allows the development of dynamical pages and animations similar to Flash during relatively short time.
The main aim of jQuery is to simplify:
jQuery’s modular access enables the creation of strong dynamical websites and applications.
jQuery library was published in January 2006 for the first time on BarCamp NYC by John Resig. Month later, was added the support for Ajax and in May the same year, the jQuery took over open source MIT licensed model.
In September 2007, jQuery offered up new user interface and started to be popular. In September 2008, Microsoft and Nokia announced their support. Microsoft has tried to use jQuery for Visual Studio by integration to ASP.NET of Ajax Framework and Nokia has integrated jQuery to its development platform on widgets.
One of the original aims, why jQuery library was created, was the time saving.
