I have been doing web apps and websites for a long time, and when I first saw this, it looked so wrong but felt so right.

Inline styles were impossible to maintain. Even if these (reactCSS) are rendered inline, it's easy to maintain, easy to follow, easy to change.

Javascript used to refer to making things move around and handling click/hover events (javascript was the DOM language). Now it's the entire application.

what am I trying to say...? it seems wrong, but try it out and see if your concerns don't just go away.
