How can I handle errors when using fetch in React Native?

You can handle errors in React Native's fetch API by using try-catch blocks or by checking the response status.

Can you show me an example of using try-catch with fetch?

Sure! Here's a simple example:

try {
  const response = await fetch('https://api.example.com/data');
  if (!response.ok) {
    throw new Error('Network response was not ok');
  }
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error('Fetch error:', error);
}

What should I do if the API returns a 404 error?

You can check the response status and handle it accordingly. For a 404 error, you might want to show a message to the user.

Is there a way to retry the fetch request on failure?

Yes, you can implement a retry mechanism using a loop or a library like axios-retry for more complex scenarios.
