Sometimes I want to import certain libraries only on certain platforms. For example, right now I might only want to import Branch or RN Maps on ios/android and not web (otherwise it won't even compile on web). I'd like to be able to conditionally import libraries in my project. One way that could work is by creating ".ios.js", ".android.js", and ".web.js" files in my project.
