Debugging in React Native helps developers identify, inspect, and fix issues in JavaScript logic, UI rendering, network calls, and native behavior. The built-in Debug Menu and Inspector tools provide powerful insights during development.
React Native debugging relies on JavaScript runtime inspection, UI hierarchy analysis, and runtime logs. The Debug Menu can be opened using gestures or shortcuts depending on platform.
// Basic console debugging in React Native
import { View, Text } from 'react-native';
export default function App() {
console.log("App component rendered");
return (

);
}
The message “App component rendered” will appear in the Metro console or debugger whenever the component renders, helping track render cycles.
