[Feedback] Looking for suggestions to improve my Pomdoro Clock!

Hey friends! I would love to get some feedback on my Pomodoro Clock!

By over-complicating the break time versus the session time, it took me a long time to get this project to where I’ve wanted it.

I would like some suggestions on how to improve the project and the overall Javascript code. I would also like to find bugs that I can work on fixing, or any design issues you might dislike. Thanks in advance!
