Additionally, I am impressed by some UI frameworks such as YUI which I like most. But meanwhile, my company formed a team named Yoolk UI team to build its own UI Framework and I am the first person to use and test it. Of course, it is hard for me to use the UI framework for the first time. Later on, I get used to it.
So far, we use our framework to build our own application. Yes, it works! It is very flexible, powerful and easy to use. Moreover, the Yoolk UI team is still continuing to improve it to be better and better.
We would like to inform all of you guys about this framework and you guys can give any good feedbacks as well. Please check it out http://ui.yoolk.com/
