React Native jaħdem JavaScript u kodiċi native li għandhom ikomunikaw. L-arkitettura oriġinali iddawwlet bridge asinkronu; l-arkitettura ġdida (JSI, TurboModules, Fabric) tippermetti komunikazzjoni aktar mabida, sinkrona. Il-fehim ta' dan jikkjarifikaw il-imġiba u l-prestazzjoni ta' React Native.
L-arkitettura oriġinali: il-bridge
React Native runs:
→ a JS THREAD (your React/JS code) and the NATIVE side (UI, native modules)
→ they communicate over a BRIDGE: messages are SERIALIZED (to JSON), passed ASYNC,
and deserialized on the other side
Limitations:
✗ ASYNCHRONOUS only (can't call native synchronously)
✗ SERIALIZATION overhead; the bridge can be a BOTTLENECK with heavy traffic
✗ e.g. fast scrolling/animations passing data over the bridge → jank
