This is actually the correct way to do it in JavaScript, especially if the right hand side is more than 1.

If JavaScript thinks i contains a string, and let’s say its value is 27, i += 1 will result in i containing 271.

Subtraction doesn’t have any weird string-versus-number semantics and neither does unary minus, so i -=- 1 guarantees 28 in this case.

For the increment case, ++ works properly whether JavaScript thinks i is a string or not, but since the joke is to avoid it, here we are.

There is no problem if both of these people are sane and are getting sane, non conflicting direction from those interested parties who are not involved in the software design.

Ha! Hahaha.

Hahahahahaha.

Oh, I made myself sad.
