It seems Javascript Toolkits have infiltrated every nook and cranny of the internet. And it seems like everybody and their nephew has built one.

So which toolkit is the right one for you?  Well, most of the big names have the same subset of features, such as “drag and drop”, animation capabilities, and XML HTTPRequest functionality.  Maybe you need something a little more, like HTML Generation or the out-of-the-box charting functionality of Dojo.  Or, your deciding factor may be licensing.  You may love the features of GWT, but your company doesn’t gel with the Apache License.

I put together the illustration below from the data available on this wiki article to compare all the big guns in the Javascript Toolkit game.  I know I left off some that you may be using, and didn’t list all of the features, but this should be a good snapshot to get you started.  Please let us know your experience with these or any other Javascript Toolkits.

Another thing we would love to know is will you be using one of these toolkits when HTML5 is “fully supported” in all the major browsers… whenever that may be?
