I just want to let people know this Documentation link: http://cocos.sonarlearning.co.uk/docs has been super awesome and super helpful in developing JavaScript games using Cocos2d-x.
I want to say good job Cocos Team and please keep this documentation up to date as the Cocos engine matures and improves with each update
We have been making other tutorials, WebVR tutorials are available on our YouTube channel. We are wrapping up our royalty free platform as well so you will have access to almost all of our artwork for free.
