Responsive website for shortening urls

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

Sharpened my skills at fetching an API, modulizing the code, making it easier to mantain and learning more about localStorage limitations.

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

First, I've came into a wall for the recommended API does not allow requests from client-side due to CORS-policy. I've spent some time trying to find an API that did the same and came across the "tiny url", which allowed me to complete the project.

I've also sharpened my skills at modularization, as I intend to make this project Object Oriented in the near future for some of my classes. So improving this skill and overcoming some walls for "how can I make this better" was a great personal achievement for me.

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

Any feedback is always welcome, but I'd love to hear what you have to say about modilarization and semmantics.
