Conclusion

Building scalable React applications requires:

1. Thoughtful Architecture: Organize by features, not file types
2. Performance Awareness: Optimize rendering and bundle size
3. Type Safety: Use TypeScript for better maintainability
4. Testing: Comprehensive test coverage for confidence
5. Monitoring: Track errors and performance in production

Remember, scalability isn't just about handling more users—it's about maintaining development velocity as your application and team grow.
