Advice generator with fetch()

Hello everyone 👋

Here is my advice generator. I chose this challenge to practice working with API and error handling. The latter proved to be the difficult part for me, so feedback on it is welcome.

1. The documentation says that when something goes wrong, you get a message object instead of slip object, but the response is still successful, so I added code for that in a then call. Is this correct?
2. You don't get the message object in case of all errors. I divided others into two categories:

• there is no body, so there was a network error and "Network Error" text is displayed.
• the error response has a body, then user gets info about the error code and message
• in both cases described above the user is asked to check Internet connection or contact (imaginary) support

How can I improve that? The way it is now doesn't seem that helpful. I'd be grateful for any tips.

Thank you and happy coding 😄
