A framework for building native apps using React.

OSX  mandatory to develop for iOS platform.

Homebrew to install Flow and Watchman.

¿ Why Should You Use React Native to Develop Apps?

You only need to learn  JavaScript  to create an app for iOS and Android platform. Learn once, write anywhere

You can share source code between projects running on different mobile platforms. Reuse code.

At the time of shipping Ads Manager for Android, that approach yielded around 85 percent reuse of app code
