What is React Native

A framework for building iPhone and Android apps from one JavaScript codebase. Built on React.

In plain terms

React Native lets a web-trained team ship both mobile apps from a single codebase. Expo is the toolkit most React Native projects use. Its concepts come straight from React for the web, so the same people can cover both. The team trades some native polish for one codebase.

What it tells you about a developer

React Native depth signals a mobile developer with web roots: React and TypeScript fluency plus app-store shipping experience. For performance work specific to one store, Swift or Kotlin depth is the closer match.
