Agreed.
And sometimes code is not the right medium for communicating domain knowledge. For example, if you are writing code the does some geometric calculations, with lot of trigonometry, etc. Even with clear variable names, it can be hard to decipher without a generous comment or splitting it up into functions with verbose names. Sometimes you really just want a picture of what's happening, in SVG format, embedded into the function documentation HTML.
Yeah. I advocate for self explanatory code, but I definitely don't frown upon comments. Comments are super useful but soooo overused. I have coworkers that aren't that great that would definitely comment on the most basic if statements. That's why we have to push self explanatory code, because some beginners think they need to say:
I think by my logic, comments are kind of an advanced level concept, lol. Like you shouldn't really start using comments often until you're writing some pretty complex code, or using a giant codebase.
I think overusing comments is a non-issue. I'd rather have over-commented code that doesn't need it, over undocumented code without comments that needs them. If this over-commenting causes some comments to be out of date, those instances should hopefully be obvious from the code itself or the other comments and easily fixed.
I understand what you're saying and I mostly agree, but those few instances where a line of code is only slightly different and the comment is the same, can really be confusing.
