I’d rather the code itself is readable with well-named variables and methods.
There are situations where comments are helpful though
// this foos the barfoo(bar);
Helps nobody
// this might seem weird, but we had to add this because some customers were complaining about unfood bars and the rest don't seem to mind either wayfoo(bar);

Unfortunately, sometimes a level of specificity is needed that can’t be expressed in a method name alone, unless you make that method name super long. The method name can’t always convey:
Time and space complexity
Side effects
Thread safety
Possible exceptions
Preconditions and postconditions
Edge cases
Sure, some of this can be communicated in the implementation, but that means that users need to control-click the function instead of just hovering to see the comment. And sometimes the implementation is a secret or at least in a different file from the declaration
