React Native Reanimated: Off-Thread Animations
Reanimated moves animations off the busy JavaScript thread onto the native UI thread. This ensures smooth, 60-120 fps performance for gestures and transitions, even during heavy JS computation.
Reanimated gives animations their own high-priority lane by running them on the native UI thread, separate from the main JavaScript thread. This prevents a busy JS thread from causing dropped frames, ensuring a fluid 60-120 fps experience. It's essential for complex gestures, screen transitions, and dynamic layouts that need to feel native. The most common footgun is forgetting that communication between the UI and JS threads requires special tools; you must use `useSharedValue` hooks, not standard React state, to drive animations.
