Advice generator with REST API

What specific areas of your project would you like help with?

I structured the JavaScript code with modularity and future testing in mind. I implemented:

• Error Handling: i.e.4xx-5xx HTTP Status
• Handle Edge Cases: validate Api Response
• Provide Feedback to Users: Loading Indicator and Error Feedback
• Debouncing the Button Click
• Accessibility Considerations, aria-busy, aria-live="polite”
• Use init()

Please comment on my JavaScript code design on fetching and display the advice from the Advice Slip API.

What area should I look into for improvement? Any good link?
