Pomodoro Clock in React

Hi, guys, it’s been almost a year since I’ve submitted the project here. I’ve been learning from different resources but I am a huge fun of FCC and I always wanted to get back and finish the all 3 paths here.
The last thing I was trying to learn was React, so I was thinking it would be nice to practice React by implementing remaining FCC projects. And this is what I got, I would really appreciate your feedback I know some parts of the code are messy and I will try to come up with cleaner solutions.
