React Native로 Native한 애니메이션 구현하기
summary
Explains how React Native Animated actually runs by tracing JS thread → bridge → native thread interactions, inspecting internal code and using a MessageQueue spy; shows a demo box animation that moves and proves the native driver avoids blocking when JS is busy. Claims a non-native driver makes three bridge crossings per frame (60 fps → 180 bridge calls/sec), causing dropped frames in a heavy app with ~1M users; native-driver batches frame math on native side and keeps 60fps.
