How do I differentiate between different types of `fetch` errors when using `await`, such as CORS errors?

CORS errors typically won't reject the `fetch` promise directly; instead, they'll result in an opaque response (you won't be able to access the response body). You can check if the `response.type` is 'opaque' to identify potential CORS issues. For other errors, inspecting the `error` object in the `catch` block might provide more information about the error type. However, reliable error type detection can be challenging with `fetch`, so focus on handling common error scenarios gracefully and providing informative error messages.
