The <!-- and //--> comment (hiding) tags have not been necessary since IE3 (i.e. since September 1997). If you see these in some published script it is a warning that you are looking at ancient and perhaps unreliable code.
"I used to think I was poor. Then they told me I wasn't poor, I was needy. Then they told me it was self-defeating to think of myself as needy. I was deprived. (Oh well, not deprived but rather underprivileged.) Then they told me that underprivileged was overused. I was disadvantaged. I still don't have a dime. But, I have a great vocabulary." - Jules Feiffer, cartoonist.

All the code given in this post has been tested and is intended to address the question asked.
Unless stated otherwise it is not just a demonstration.
