Summary:
public
The current `ScrollView.scrollTo()` API is confusing due to the `(y, x)` parameter order, and the boolean `animated` argument. E.g.
ScrollView.scrollTo(5, 0, true) // what do these arguments mean?
This diff replaces the API with a configuration object, so the arguments are all explicit:
ScrollView.scrollTo({x: 0, y: 5, animated: true}) // much better
The `scrollTo()` method checks the argument types, and provides backwards compatibility with the old argument format for now. Using the old API will generate a warning, and this will eventually be upgraded to an error.

UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
