jQuery

jQuery can be used for DOM traversing, JS event handling, Web-based animations and running Ajax interactions.

The library simplifies the way JavaScript has to be written and is suitable for a wide range of Web applications.

jQuery benefits from thousands of open source and commercial plugins developed by its dedicated community and also features one of the best documented codebases around.

The library is incorporated in most CMSs and blogging platforms around and is also hosted on various CDNs for improving delivery times, ranging from Google up to Microsoft.

According to the Builtwith.com statistics service, jQuery has been used on around 64% of all the Top Million sites on the Internet, percentage that goes even higher to ~65% for the Top 10000 sites.
