Ask HN: Experienced JavaScript Hackers – Can you please review my code? :)

I recently built this minesweeper game for Node.js. The github link is here <https://github.com/fej-snikduj/minesweeper-nodejs>

I'm relatively new to programming, and recently completed a 3 month bootcamp. While I thought the course was great and we learned a lot of different frameworks, I did think there was too light of emphasis on creating quality code - it was kind of the bind leading the blind in that case.

Now that I'm starting a job search, some feedback from experienced JavaScript hackers would really help me out.

I'm looking for comments on: styling, structure, readability, modularity, proper use of comments, and even proper git etiquette. Feel free to comment, or shoot me a message. And please feel free to rip it apart - I only stand to learn.

Thanks in advance!
