Answer

  1. Use try/catch blocks with async/await for clean error handling.
  2. Make use of the .catch() method when working with promise chains.
  3. Inspect the response status to handle different HTTP errors (e.g., 404, 500).
  4. Implement global error handling using window.onerror or similar mechanisms.
  5. Provide user feedback based on the error type.
