React has been out for two years and still only has about 20% of the market share of Angular if you do a job search on Indeed.com. In theory, React has a much shorter learning curve than Angular, as it is a lot closer to say. JQuery concepts, without the concept of factories, services, scopes, etc. But in practice, it hasn’t really gained the same adaptation of Angular, partly because it does not cover the full MVC concept, partly because Angular is just . . .plain amazing once you get used to it. The complete separation of HTML views and Javascript services is revolutionary.
Reactive Native is basically, Appcelerator Titanium with React API. It will recompile your JS code into fully native apps, instead of a web page wrapper like Cordova/Phonegap. This has significant advantage in performance, at the cost of compatibility.
What I would like to see:
Google buys Ionic and coupled with Angular 2, one platform to rule them all.
OR
Facebook releases the official Facebook app as a 100% React Native app, and React/ React Native dominates as the top choice.
What will probably happen:
Neither company is 100% serious about these projects, and we continue to have flawed products and a divided market . . .
Seriously, jokes aside, I am still waiting for that hero app for hybrid platforms. It is funny in gaming (which requires much more performance), both Cocos2D and Unity 3D have countless top 10 grossing games with tens of millions of downloads to prove their dominance.
In apps, we are still waiting for a hero app for Ionic and/or React Native, and no Facebook Ad Manager is not it.
