React Native is a platform for building native apps that uses the latest and greatest in web technologies such as React and React Native, as well as technologies from the SPA ecosystem. Unlike other platforms that use a separate framework, such as App Engine, which is used for web development, React Native is a single source of truth. This means that you can’t mix and match technologies between your apps. You can’t mix app code and resource code, or write code that accesses data from an outside source. Using this approach, you not only get the best of both worlds: code and data, you get everything.
