I agree with some of your points, but I also see "best practice" more on the concept level. I'm voting best practice for the approach & solution to the problem.

camelcase vs snake case is personal preference.

I agree with the first part but I find the answer's ternary expression much more readable than yours.

lol. You are a perfectionist or haven't seen enough bad code 😄

btw, I agree with all your arguments.
