React Native Performance Book: 2 Books on React Native Performance and a Profiling Tool.

React Native is great. For a lot of reasons. However, performance is not one of those reasons. It takes additional scrutiny and foresight to build performant React Native applications. Anybody building production apps with React Native should learn about how to make (and keep) your application performant. There's multiple resources on this topic but this looks like a good investment to make. I've purchased the book and will update my comment here after going through it. UPDATE: Be aware that the two "books" are a total of 65 pages with a large font. It's certainly not exhaustive and is likely something that will be continually updated as per Adam's message: "This is just the start of both books and the profiling tool."
