Help with Pomodoro Clock Timer Logic

Problem

I am kind of stuck on getting the clock logic to work for the Pomodoro Clock project, I’m curious if someone check out my code on CodePen and perhaps give me some guidance. Everything else feature wise is working, and once I figure out the timer logic, I’m confident I can return the timer data in MM:SS format. :smile:

Thanks in advance for the assistance!

Your code so far

Can be seen on CodePen: https://codepen.io/jpvajda/pen/zYxKpbG
