i'm taking note of this website right now

it seems that there's really a lot of javascript framework/ui for mobile and i'm interested to find which one offers the best performance/ui ratio

I am trying to learn Javascript, coming from a Perl / Python / RDBMS background.

What a mess the JS landscape is. There are so many frameworks, and no clear reason to choose one over the other. Angular has a reputation as being one of the better ones, but it seems overly complex, the documentation is terrible, and the learning curve is steep. And its still one of the better of the ones that I have tried.

chocolatechip-ui is a nightmare, at least for me. It has tons of micro-issues. Mostly just awkward interaction / behavior and missing key basic features.
