There are some cases though where the code is just complicated for reasons outside of your control, in which case “what” comments are good - but they should never be taken at face value, but only used as a first step in understanding the code. There’s a significant risk of the code not actually doing what the comment says.
Yeah. Most of the time I use comments in my algorithms, as they often use some weird optimized black magic which are difficult to understand without comments.
Comments should only be used to describe stuff that’s otherwise difficult to convey with code.
The best explanation I’ve ever heard is:

Like don’t set this value to the obvious default. Bad stuff happens
