Responsive Time Tracking Dashboard Using HTML,CSS,JS along with JSON

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

Utlizing the JSON file to get data for the first time.

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

Using JSON was really difficult and took a lot of research to get through

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

As you can see in the JavaScript Code I have some comments in nextFunc() which were not giving the proper output like:

const val = timeframes.${clickedId}.current; const value = element[val];

This is giving me undefined output and due to that I had to use a brute force method. I would love to know what was wrong in this and any other advice /suggestion will be helpful

This was my first time using JSON so I don't know whether it is correct or not.
