One Codebase, Seven Platforms: How React Native Changed Cross-Platform Development

React Native has matured from a mobile-only framework to a comprehensive cross-platform solution targeting 7+ platforms—iOS, Android, tvOS, Vega OS, Meta Quest, and more—with mandatory architectural improvements and 55% performance gains via Hermes. Enterprise adoption from Shopify, Microsoft, Discord, and others validates the framework's production readiness. For development teams and businesses, this represents a fundamental economic shift: one codebase now replaces five separate native projects, cutting development costs and timelines by more than half while eliminating multi-team coordination overhead.
