-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.

-Notice that the exported method name was generated from first part of Objective-C selector. Sometimes it results in a non-idiomatic JavaScript name (like the one in our example). You can change the name by supplying an optional argument to `RCT_EXPORT`, e.g. `RCT_EXPORT(addEvent)`.

-The return type of the method should always be `void`. React Native bridge is asynchronous, so the only way to pass a result to JavaScript is by using callbacks or emitting events (see below).
