React Native lets you write a single codebase that runs on both iOS and Android platforms. You write JavaScript components once and compile them to native code for each platform, avoiding duplicate development while maintaining native performance and platform-specific features.

Native modules bridge JavaScript to native device APIs through platform-specific code. React Native handles the communication layer, letting you access hardware features like camera, GPS, and sensors by writing native modules or using pre-built community packages that wrap platform capabilities.

Performance optimization in React Native involves memory management, render efficiency, code splitting, and lazy loading. Key strategies include profiling with native tools, minimizing bundle size, optimizing list rendering, managing state effectively, and tuning startup sequences to reduce time-to-interactive.

Publishing requires building release binaries, managing signing certificates, and navigating app store submission processes. React Native provides tooling to generate signed APKs for Android and IPA files for iOS, followed by app store account setup, metadata configuration, and review submission for each platform.

Yes. React Native supports production-grade architectures including MVVM and Clean Architecture patterns. Combined with state management libraries and React Navigation for routing, it handles complex user flows, data persistence, and enterprise-level requirements across both platforms reliably.

React Native provides platform detection and conditional rendering to handle iOS and Android differences. You can use Platform modules, platform-specific file extensions, and branching logic to execute different code paths, ensuring consistent user experience while respecting platform conventions.
