ReactNative vs Flutter
Key difference from Flutter: RN uses native UI components through a bridge JS code runs in a JavaScript engine Only the native platform code compiles to ARM64 Performance overhead due to bridge Flutter: Direct compilation to ARM64 No bridge Own rendering engine Generally better performance
