This week’s presentations cover a few Javascript frameworks, including EXTJS, JQuery, GWT (Google Web Toolkit), and YUI (Yahoo! User Interface Library). All open-source, customizable libraries, these Javascript frameworks offer various tools and plug-ins for building richly interactive web apps.  Examples are animations, utilities, controls and widgets.
Be sure to check out our archived presentations that cover RIA technologies and runtimes, programming languages, and other frameworks.
