Dojo is a JavaScript toolkit for building Web applications, of course, open source. Its goal is to provide a set of specially constructed APIs and a series of assistive tools that will enable you to translate ideas into implementation in a relatively short time while improving your daily web development experience. It is fast (lightning fast), robust (lightning fast), and provides a set of tools that can handle dom,animations, Ajax, events, keyboard manipulation, internationalization (i18n) and accessibility (a11y). The Dojo Base library is a 26K sized, lightweight file that can be easily downloaded ("Across the Wire"). Dojo is completely free and has a loose license agreement (AFL or BSD). The development of dojo is transparent, with a group of active developers and a strong community behind him.
Regardless of the size of the project, Dojo offers the ultimate scalable solution to your development bottlenecks. The built-in package mechanism ends the headaches of tracing dependencies (tracking dependencies), which can be built into cohesive, optimized multi-tier code for publishing. DHO makes unit regression testing an easy task.
Plug - ins
In addition to all the features available in Dojo.js, you can also use the powerful package mechanism to increase the functionality of your program through Simple Dojo.require () calls. Dojo's core features include drag-and-drop, advanced AJAX transmissions, string processing, powerful data APIs, and hundreds of other features that allow you to easily build rich Internet applications.
