Today I read a blog about React Native, and I was amazed to see that Facebook, Instagram, Airbnb uses this.
Is it already a thing now, thinking of giving it a try
There is so much confusion out there for a mobile developer what platform to choose, btw m developing native android apps from past 3 years.
What are your thoughts on it?

I don't have mac!!!
End of the story for me, and I went back to native Android.

Facebook developed it, so you'd like to hope they're using it! I've been dabbling myself, but finding it hard to really get into it.

I've developed a simple app with it. Styling is a pain but it's probably even more painful on Java.

It's pretty easy and fast to get up and running. But I don't really know if it's a smart idea to develop production app with it, seems somewhat constrained.

If you have front end dev experience you'll love react native.

It's rather awesome, tho creating an app with complex navigation (esp with redux and all that jazz) is quite a hassle. I'd say that if you have at least some background with react you'll feel like home, except for that navigation part. We've spent good one week just figuring out how to stitch all the views together so that it makes any sense - but it was fairly complex app with plenty of nested views and so.

Done a bit there. Easy to learn and a bit hard to style.
Testing it out on a simulator is pain in the ass. And that discourages me doing projects on React-Native.
Otherwise nice underlying concepts of components and state.
