I guess I thought Sencha Ext JS and Touch were more popular in market. But since your article doesn't even mention them, I'm guessing that is not true. I began using Ext JS and now Touch in past few years as the front end for applications using data on my IBM i5 server. I'm definitely sold on the JS/HTLM5/CSS3/AJAX approach, it's been terrific.
I'd heard of JQuery and to a lessor degree, Angular. I had never heard of those others you mentioned in the search results until this article.
Makes me wonder what the learning curve is if you know any of these to use another flavor? I've seen JQuery syntax, would not be hard to move to it from Ext JS. But know nothing about these others, including Angular. Just another example of how fractured the programming market is now, even within the JS/HTML5 subset. Then you still have the MS languages, Java, Ruby, Python, etc, etc, etc. Even worse in my mind is proprietary companies like Facebook and Google creating languages. These guys aren't IT providers like MS or IBM, I'm not sure every IT product oriented company needs to be creating languages for general business use. Doesn't give me a warm and fuzzy. :-(
