Michael Cantera, there isn’t a better time to try out React Native than now. With Sketch by Expo (“JSFiddle for Native”) and create-react-native-app having been released this weekend, you can make native apps on any machine (including Windows!) without installing any native tools.
This is made possible by expo.io, which comes with pre-built native binaries. The only limitation is that you can’t include custom native modules — but Expo comes with many of the most common ones built-in.
