How do I handle CORS errors in my React code using `fetch`?

While you can't directly fix CORS errors from the client-side, you can handle them gracefully. Wrap your `fetch` calls in a `try...catch` block. If a CORS error occurs (typically a 403 Forbidden or a network error), the `catch` block will execute. You can then display an error message to the user or log the error for debugging. Note that the browser might not provide a detailed error message in the console due to security restrictions.
