Reviewer scorecard
“One tool replacing Prettier + ESLint with massively better performance. The migration from existing configs is smooth.”
“EAS Build, OTA updates, and the managed workflow eliminate the worst parts of mobile development. Indispensable.”
“The speed improvement is not a micro-optimization — it changes CI feedback loops and editor responsiveness.”
“Expo has matured from toy to production platform. The config plugins and custom dev clients removed the old limitations.”
“Rust-based tooling replacing JavaScript tools is the trend. Biome is the most impactful example.”
“Expo is making React Native the default for mobile. Universal apps (web + mobile) from one codebase is the future.”
