Next level: Now I have to learn to create 3D models with Maya, Cinema4D or Blender as a web developer :)
In case anyone's missing context, there have been a few WebVR renderers for React, some built on top of A-frame, some native WebVR. ReactVR is a new, currently preview, release of a Facebook-built VR React renderer.
It was announced at the Oculus Connect dev conf in October 2016.
React gets a lot of things right but the technology is not exclusive to JavaScript. We will see adoption of similar approach in other languages with potentially portable views and semi-portable business logic (more decoupling I suppose).
In terms of ReactVR - yes it is pretty cool.
I can see a bright future for JavaScript
