Responsive IP Address tracker using Leaflet.js

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

I am proud of doing this Map and IP bases API project. I would like to write less lines of code next time.

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

Using the map and marker was a challenge as this is my first project using Leaflet.js but using their documentation, I did it quite easily.

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

I would like help with anything related to my javascript code because I think I am a little bad at it.
