I would like to ask you about ReactJS developers forum or site.

The Developer Forum is https://www.reddit.com/r/reactjs/

Any good tutorials or tips? https://www.sitepoint.com/javascript/react/

http://www.tutorialspoint.com/reactjs/

Video lectures https://www.youtube.com/watch?v=MhkGQAoc7bc&list=PLoYCgNOIyGABj2GQSlDRjgvXtqfDxKm5b

That's about it.

I just searched on Google and organized the sites~

This is an email I received 2 months ago from the famous site Codecademy.

ReactJS is not currently available, but

Sass was opened a while ago, and the reaction is expected to be opened soon.

Please keep that in mind.
