1What is the main role of Metro in a React Native project?
What is the main role of Metro in a React Native project?
Cevap
Metro is React Native's JavaScript bundler that compiles and bundles JavaScript code into a single file for the application. It also handles Hot Module Replacement (HMR) in development, allowing developers to see changes instantly without restarting the app. Metro transforms ES6+, TypeScript and JSX code into JavaScript compatible with the device's JavaScript engine.

Which command opens the developer menu on an Android emulator?
Cevap
On an Android emulator, the Ctrl+M shortcut (or Cmd+M on Mac) opens the React Native developer menu. This menu provides access to options like reloading the app, enabling Remote Debugging, inspecting elements with React DevTools, and toggling the Performance Monitor. On a physical device, shaking the device also opens this menu.
