## Extensibility
It is certainly possible to create a great app using React Native without writing a single line of native code, but React Native is also designed to be easily extended with custom native views and modules - that means you can reuse anything you've already built, and can import and use your favorite native libraries. To create a simple module in iOS, create a new class that implements the `RCTBridgeModule` protocol, and add `RCT_EXPORT` to the function you want to make available in JavaScript.

Additionally, the class itself must be explicitly exported with `RCT_EXPORT_MODULE();`.
