So FB mixes this and react native in their app?

  We use both at Facebook! React Native works cross platform whereas Litho provides performance that beats the Android Toolkit - so they are each beneficial for different use cases. Litho is heavily inspired from RN so the programming model should be familiar.

  If I remember right, this was created before React Native. And, they still do have a lot of Android code in the app, even with RN.
