Dojo, one of the leading open-source libraries and widget sets for JavaScript programming, released its latest version (1.2) yesterday. Dojo, which is developed by the Dojo Foundation and released under both the BSD License and Academic Free License, is officially integrated with a number of Web development frameworks, such as Django and the Zend Framework, and by vendors such as IBM and Sun Microsystems.

Yahoo announced yesterday that it was releasing version 2.6 of its popular Yahoo User Interface (YUI) library, a collection of JavaScript objects and functions for client-side Web programming. YUI, distributed under the BSD license, is similar to such open-source JavaScript libraries as jQuery (see related story), Dojo, and Prototype/Scriptaculous. Note that this release is not the same as YUI 3.0, a preview of which was released earlier this year, and which will not be backward compatible with version 2.x.

Are you using Ajax in your web application? If so, then you're probably using an open source JavaScript library, as well. Google announced earlier today that several popular JavaScript libraries, including Prototype and Dojo, will be freely available for web applications to incorporate in their HTML pages. By using Google's Ajax API, applications will be able to benefit from Google's fast content delivery network, as well as from the fact that browsers cache JavaScript files. So if any other application uses Google's copy of Prototype, your application will be able to used the cached version, saving time and bandwidth.
