True, and I do like this a lot. There's a great ecosystem, and the examples are usually pretty good.

But it's also just as easy to get stranded with missing features or features that aren't on both Android and iOS. I did a bunch of geolocation and mapping a while back and I had to write my own support for things like heatmaps. This was eventually merged into the react native maps library, but it is something that can happen if you're doing anything slightly exotic.
