Need help with selecting a framework

[8bitDev]

Hi guys

I am new here and so far i was using GUI game engines to create games.From all back-end testings so far that i done on various programming languages and scripting languages i realised that html5 is best solution for my game development.Now i decided to ditch game engines and learn actual coding in some of the frameworks so my code could be much more cleaner,run faster,have better optimization and quality of the games would overall be better.But this is not just for games,but also for personal reasons because i like to be properly educated instead of using most convenient tools.

Now i am interested in learning some js framework that has good community support and tutorials,that is easy and fast on learning and performance and if possible to implement in Ubuntu SDK.

Also i am mainly using GNU/linux and one of the reasons why i would like to use js is to be mobile and OS independent.but from all OS so far Ubuntu SDK seems like a decent solution for cordova runtime,i tried to use it with phaser but i did not succeed to render cordova runtime instead it was in plain web view.

Now overall it does not have to be Ubuntu SDK,but i am interested in HTML5 framework that i can port(wrap) to desktop mainly(mobile would be good to).

Any ideas what's the best and why,please write down below,it would help me a lot.

Regards
