React Native paleide JavaScript ir natyvųjį kodą, kurie turi komunikuoti. Originali architektūra naudojo asinchroninį tiltą; nauja architektūra (JSI, TurboModules, Fabric) įgalina greitesnę, sinchroninę komunikaciją. Supratimas apie tai paaiškina React Native elgesį ir našumą.
Originali architektūra: tiltas
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
