rest-countries Angular17, interceptors, errors handle, leazy loading

What are you most proud of, and what would you do differently next time?

I am proud of the performance of the app, and lazy loading of both images and pages. For the next time, I would like the loading modal to be displayed until everything in the viewport is rendered and not just until the HTTP response is confirmed.

What challenges did you encounter, and how did you overcome them?

Definitely the biggest challenge was realizing that I couldn't achieve that type of selection with a select tag, as I couldn't apply all the styles to the collapse.

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

I have a couple of errors in the console. One is due to change detections and the other is due to an undefined error when rendering the flag image on the inner page. If anyone can help me, it would be great.
