What else am I supposed to put in the function comment...

In my opinion could should be readable by itself, except apis.

And of course sometimes there is a piece of code that needs a comment.

This forces you to write better code and if you need some hint what the line does you could look in the versioncontrol

@TheNewGuy Well it is readable by itself - that only exists so that the function shows up in Doxygen

and you have to maintain the comments - as they are always possibly outdated

@CraftedCart kk

@TheNewGuy some IDEs will warn you if the Jsdoc markup is out of date

@620hun

you will still have to maintain the comments - and I am lazy :P
