9. - Call ‘RCT_EXPORT_MODULE();’ macro
- Export using ‘RCT_EXPORT_METHOD’
How to add your own stuff?
- Call it with MyClass.addEvent();
- React converts types automatically

10. How to add views?
- Use ‘RCT_EXPORT_VIEW_PROPERTY’ to
export view properties
- Implement ‘view’ method that returns UIView

11. What else?
- Amazing animation framework ‘Animated’
- Clojurescript already able to target iOS
- GraphQL like patterns soon be ready
- Focus shifts to user
- Sadly not available for android (yet)
