Where to find the best learning resource for Cocos2dx JS?

I can’t find the any latest learning resource for the JS version of Cocos2dx JS

Cocos2d-js has been replaced with Cocos Creator.

https://docs.cocos.com/creator/3.1/manual/en/

Seems like there is no support for linux for Cocos creator…
Is there any option I can use linux to develop with Cocos creator?

No supported options currently. I don’t see it changing any time soon.
