„Dojo is an Open Source toolkit that allows you to easily build dynamic capabilities into web pages and any other environment that supports JavaScript. Dojo provides components that let you make your sites more useable, responsive, and functional. With Dojo you can build degradeable user interfaces more easily, prototype interactive widgets quickly, animate transitions, and build AJAX-based requests simply. Dojo layers these capabilities onto a lightweight packaging system which forms the core of Dojo. When you write scripts with Dojo, you can include as few or as many of the available APIs as you need, and your app will only include what it uses.“
