Commenting well is a highly advanced skill. I generally prefer no comments on code since it's less likely to confuse people and I'll merrily purge auto-doc comments and anything like
That comment has negative value.
Comments should only be used to describe stuff that’s otherwise difficult to convey with code.
The best explanation I've ever heard is:
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.
