Dojo JavaScript framework

Optimizely Content Management System (CMS) uses the Dojo Toolkit as the JavaScript framework to develop on the client side.

The Dojo toolkit is a client-side framework for building rich internet applications hosted in a web browser. Dojo is an open-source framework that helps speed up the development of cross-platform rich internet applications by giving you a lot of features. Some key features include:

• Rich UI widgets using the Dijit widget system
• Asynchronous communication
• Class declaration and modular development
• Desktop and mobile support

The Dojo Toolkit consists of three main components:

• Dogo is the framework's core API and contains features for DOM manipulation, class declaration, event listening, message publishing and subscription, and asynchronous requests and processing.
• Dijit is the user interface system built on the Dojo core. Its primary feature is the widget system, which manages and manipulates visual elements in a modular manner.
• Dojox is a collection of sub-projects built on top of the Dojo core. It can be considered a repository of Dojo plugins or a testing ground for new features that will eventually become part of the Dojo or Dijit namespace.
