Dojo vs YUI javascript framework

Question

I want to know what you guys think of these 2 frameworks, in terms of:

• robustness,
• code quality,
• core developers moving forward with new features,
  
• cross browser problems,
  
• module components,
  
• easiest to learn and integrate
  

I already know and use jQuery, I recently found it lacking in terms of 'enterprise ready' components for large web app.

Now I don't want to start a debate on jquery, or why mootools is not in there, I want to know what you guys think of these 2 frameworks specifically.

Thanks!

Answer 1

I think your reason for rejecting jquery sounds suspicious, and recommending a framework as "enterprise ready" is a backhanded compliment in my book.

However, I have a lot of experience with YUI (2 and 3) and I think it might fit your use-case.

• Robust - YUI is used internally by Yahoo, so that should give some clues as to its robustness.
• Code Quality - I'm a contributor to the project, and the code quality is very good. As it is open source you can take a look for yourself.
• Moving Forward - It is backed by Yahoo (but also incorporates community contributions) so moving forward it is pretty safe. Again, you can track development and community involvement yourself.
• Cross Browser - it supports all the Yahoo A-grade browsers
• Modules - there are a ton, and (especially in YUI 3) it is easy to incorporate just the pieces you need. If you want mostly GUI modules, you'll still need to mix in some YUI 2 (which is easy to do). Widgets in YUI3 are coming soon, though.
• Easy to learn and integrate - YUI has probably the best documentation of any JS library I've seen. However, YUI 3 is very opinionated about how you write your javascript. It is opinionated in a good way and gives you a lot of bang for your buck, but to just "drop in" to an existing project YUI 2 may be easier.

There is no single answer. Check this page and pick the one that fits your needs:

Answer 3

YUI has a great testing toolkit and doesn't pollute the global namespace. Also, YUI test results can be read by JUnit, which is a plus in my book. I haven't used Dojo so I can't comment on it in detail, but the way it integrates with the DOM is worthy of notation.
