React: Not Just a Popular Library
summary
Argues React’s model is portable to native iOS: same component and flexbox layout shared patterns, live reloading and Chrome debugger, and shipped apps (Facebook Ads Manager is 100% React Native; Groups is 50/50). Architecture runs JavaScriptCore on background thread while main thread applies buffered view mutations over a bridge to avoid GC pauses; native modules export with RCT_EXPORT. Demonstrations show fast iteration and native-feeling UI, with caveats around animations, App Store updates, and platform-specific UI differences.
