• Today there are several high-quality JavaScript
  toolkits available and several hundred other
  toolkits of varying quality and completeness.
  Why, out of that sea of possible options, should
  you choose Dojo?

A Simple Review The Dojo

• Breadth and Depth Dojo is the full stack.
  Instead of cobbling together components from
  several different sources, Dojo allows each
  component to build on a trusted set of
  high-quality building blocks by providing
  integrated infrastructure and a wide variety of
  optional modules. These components provide good
  solutions to common user experience problems and
  can be easily tweaked to meet your needs. From
  pane-based layouts to client-side charting and
  graphing to data binding to a time-tested module
  system, Dojo is solid infrastructure for
  delivering great experiences.

A Simple Review The Dojo

• Quality Infrastructure for internationalization
  and accessibility is woven through the entire
  fabric of Dojo. Keystrokes are hinted correctly.
  The components all fit together as a cohesive
  whole. Everything is customizable easily with
  CSS, but very little needs to be tweaked to get a
  great looking UI nearly everywhere. These are the
  hallmarks of a system which has been designed and
  tested to deliver great experiences, not only to
  users, but also to designers and developers.

A Simple Review The Dojo

• Performance Dojo is used on high-profile,
  high-traffic sites every day and Dojos build
  tools are a key reason why. Dojos package system
  makes it easy to manage large-scale UI
  development projects and the build system layers
  on top to make your applications scream all
  without code changes. Dojo also packs
  high-performance implementations of common
  utilities into its core, and the rebuild of Dojo
  for 0.9 focuses heavily on performance and
  reduced code footprint. The result is a small,
  tight toolkit that is blazing fast. Dojos
  performance alone makes it an ideal platform to
  extend and build on.

A Simple Review The Dojo

• Community Dojo is an open community. As a result
  many individuals and companies have been able to
  come together on a level playing field to build
  tools that benefit everyone. The licensing of the
  toolkit is designed to be as apolitical as
  possible and we work hard to ensure that getting
  your itches scratched is easy if you are willing
  to get involved.

A Simple Review The Dojo

• MochiKit MochiKit is a high-quality JavaScript
  toolkit which makes writing JavaScript as
  pythonic as is reasonably possible while still
  achieving good performance. It follows many of
  the same conservative principles about packaging,
  naming, and global namespace usage as Dojo.
  Authored primarily by Bob Ippolito, it has great
  docs and tests but unlike Dojo does not ship with
  a widget system or extensive component set.

A Simple Review The Dojo

• PrototypeScriptaculous These pervasive
  libraries provide much of the same functionality
  as Dojo Core but do not share the same
  conservative philosophy regarding global
  namespace contention, favoring shorter naming of
  commonly used functions over other concerns.

8
A Simple Review The Dojo

• YUI YUI is developed in-house at Yahoo and
  features extensive, high-quality documentation
  and examples. Designed for speed and targeted at
  a population of professional PHP developers, YUI
  is designed with the needs of Yahoo-scale
  applications in mind. A growing list of controls
  is available with the toolkit as are useful CSS
  normalizing and layout style sheets.

A Simple Review The Dojo

• JQuery A minimalist system focused primarily on
  operating on existing DOM structures, JQuery
  features a hybrid XPath/CSS query language (Dojo
  uses standard CSS 3 queries) and provides a rich
  set of options and operations on the results of
  these queries. JQuery packs Ajax, effects, and
  other utilities into a small core (beating all
  but MooTools).

10

• EXT Like Dojos Dijit system, EXT is a component
  library. It features a large number of
  consistent, good looking widgets with an emphasis
  on pixel-perfect layout and desktop-like UIs
  across browsers. Originally developed to run on
  top of YUI and later JQuery, EXT now has its own
  low-level library, removing the need for 3rd
  party dependencies.

11

• GWT Directly integrating server-side development
  and client-side development, GWT takes the
  perspective that JavaScript is a bug to be solved
  and uses advanced compiler technology to allow
  developers to write in Java and generate dynamic,
  JavaScript based UIs in the Google style.

12
For the sake of comparison, Dojo

• Allows external committers and uses CLAs (like
  GWT or Apache) to ensure that there are no IP
  issues
• Is very liberally licensed and provides anonymous
  SVN access to everyone. Committer privileges are
  earned
• Provides a relatively rich client-side component
  set but does not require tight binding to any
  server-side language (protocols, not APIs)

13
For the sake of comparison, Dojo

• Attempts to provide a balance between on-the-wire
  size and common-case functionality. Do
• Is very conservative about not stepping on the
  toes of other code in your pages and preserving
  the global namespace jo Base is similar in size
  to Prototype

14
For the sake of comparison, Dojo

• Is edge-cached on AOLs CDN for use by all
• Provides a package system which makes knowing
  which order to load things in a moot problem
• Allows for incremental enhancement via markup and
  provides a very easy-to-use widget system for
  building your own reusable components which can
  then be easily instantiated via markup
