Reviewer scorecard
“10x faster package installs, native TypeScript, and built-in test runner. It's replacing Node.js in my new projects.”
“EAS Build, OTA updates, and the managed workflow eliminate the worst parts of mobile development. Indispensable.”
“Speed is real and measurable. Node.js compatibility is good enough for most projects. The future of JS runtimes.”
“Expo has matured from toy to production platform. The config plugins and custom dev clients removed the old limitations.”
“Bun is forcing Node.js to improve. Competition in runtimes benefits everyone. Speed + DX is the winning combination.”
“Expo is making React Native the default for mobile. Universal apps (web + mobile) from one codebase is the future.”
