Nintendo Drum Machine Project Feedback

I was wondering if anyone could provide feedback on this Nintendo Drum machine project, and I also had a couple of questions:

  • I created this Drum Machine with the help of Wes Bos’ JavaScript 30 course, and I was wondering what the best method would be to refactor the code so that it can pass Free Code Camp’s user stories.

  • If you’ve completed this project using React, what was your experience like? I’ve just recently completed FCC’s React challenges, and although I was able to go through each challenge without too much trouble, I don’t feel very confident with my React skills yet.
