Answer

  1. Try/Catch: Use try/catch blocks in async functions called within useEffect or event handlers to catch any errors.
  2. State Management: Create a local error state to store and display error messages to users if an API call fails.
  3. Error Boundaries: Implement error boundaries that catch JavaScript errors anywhere in the child component tree, allowing for graceful error handling.
  4. Logging: Consider logging errors to a monitoring service for later analysis, helping to identify and correct issues in the application.
