## js -> native

- [Simple Example](https://gist.github.com/chourobin/f83f3b3a6fd2053fad29fff69524f91c#file-simple-example-md)
- [Callbacks](https://gist.github.com/chourobin/f83f3b3a6fd2053fad29fff69524f91c#file-callbacks-md)
- [Promises](https://gist.github.com/chourobin/f83f3b3a6fd2053fad29fff69524f91c#file-promises-md)
- [Properties (for UI)]()

## native -> js

### Events

Keep in mind:
- Events share namespace (so come up with a naming convention)
- If you have several instances of a component, you need to pass an identifier (like a view's `reactTag`) to identify it in the handler.
