The real answer is it's not A or B. Comments matter, but don't scattershot them either, better written code can make it so it's less comments, not commentless.

Humans are not infallible beings, even code written with the perfect intent can have bugs in it, or be overly rigid and inflexible, caused by moments of fuzzy logic coming from the meat side.

Without comments though, when that fuzzy code breaks, then nobody else will know what the original intent was and will then have to waste time either deciphering the intent and then fixing the one or two badly written lines out of the thousands, or rewriting the whole thing from scratch.

Also, there's the other factor you're ignoring. There's no infallible programming languages either (especially JavaScript, king of inconsistency.)

Intuitively you'd assume that !nullyValue is always going to behave the same, but that's just straight-up not true for all instances, and you need comments to go // known bug with Firefox v12, have to use this none-standard pattern as workaround

Comment your public methods >:c

Literally working on a legacy project atm, opened up one file that was over 14k lines long amd had several hundred methods shoved into it, not a single comment to be found.

Not auto-generated, just lazy coders over 10+ years that kept shocking shit into this class willy-nilly with no regard.

There's largely 2 places for comments:

1. Public methods should always get documented

2. Anytime you have to explain why. You don't typically meed to comment the "what does this do" part unless you've written something very difficult to read for optimization reasons. But anytime you would have to explain "why did you do that", you absolutely comment that.

Basically if someone else reads the code and you have a section that would make them go "wtf, why did they do it that way", and you'd respond with "ah yeah so it's because if you don't do it that way this other thing happens"... then you absolutely must put a comment in.

Comment anything in your code up to an ungodly amount! Code is for humans to read. The computer does not care about the comments.
