React Native

Definitions

1. A framework for building native mobile apps using React and JavaScript/TypeScript. Unlike hybrid apps (WebView), React Native renders using actual native UI components. The New Architecture (Fabric renderer, TurboModules, JSI) bridges JavaScript to native code without the old async bridge bottleneck. Used by Meta, Microsoft, Shopify, and Discord.

   In plain English: A framework for building real mobile apps for iOS and Android using React, sharing most of the code between platforms.

   Example: "Write the app once in React Native and deploy to both iOS and Android -- 90% of the code is shared, with platform-specific modules where needed."
