In the React Native case specifically, I've found that searching github issues is often super helpful. The project is very popular, changing really really fast, and still has a bunch of rough edges. So if something really seems wonky (and isn't a bizarre use case), it's pretty common that someone has already brought it up there. Reading the code is pretty much always a good idea, too.
