package-lock.json and yarn.lock

as far as I know, these two lockfiles are not automatically kept in sync, i.e. yarn does not modify package-lock when it adds a dependency. Perhaps it is better to just settle on using one or the other?

+1 to that! It would also be important to create a CONTRIBUTING doc so you can document that one package manager is the preferred for this project, as well as making sure that anyone that wants to contribute with a pull request needs update the preferred lockfile before it can be merged.

FWIW, I really like yarn but I'm usually in favor of keeping npm as the standard for OSS projects, because it is inherently more popular.

Personally I've been using npm. However, I have no strong preference for any of the two. Should we use npm because it's what Facebook uses in the React Native tutorial?

Up to you, just better to pick one and stick with it (afaik) (and delete the unused lockfile).
