For a couple of years I had done full stack work on an e-learning application that when from Ember to Angular. For the last year and a half though I have been working specifically in backend.
Recently I started doing some light work with React and I think the biggest difference between Angular 1 (even Ember to some extent) and React that I have found is Flux (https://facebook.github.io/flux/). Technically Flux is a "pattern" but I believe it is more or less required if you plan to do a non-trivial application in React.
I won't give an opinion about it since I haven't really worked long enough with React to really do so, but I thought I would mention it for you to consider.
