There is a ton of helpful stuff in dojo and it is getting a lot better and more. Even the documentation is becoming better, so don’t hesitate to try it out! And there are some little pieces that you see coming every day that are being added to dojo to help.
There is for one the daily (if not hourly) progressing API viewer.
And there is the new dojox.help stuff.
And as a tiny little bit I also have added a piece (the apropos command) that probably gets added into the dojox.help namespace.
Stay on the pulse of dojo!
