Hi I have a very simple question, which u may even consider stupid.
When do u use constans? For example in functions or while defining something.
What do they exactly do?
It may sound like a newbie question but i more or less writed some plugins for sourcemod since winter 2016. And i never used constants. I created many plugins for my server like my own jailbreak game/warden system, vip plugins, slots etc. Or edited many plugins, but i still don't get what constant does and what can u gain from using that.

constant variables are variables that never change.

If you mean the 'const' keyword, it simply makes it so you can't modify the value of the variable after it is initialized. Very useful for minimizing human error when you have a variable that's never meant to change, the compiler will throw an error and let you know immediately rather than having plugin failing later and making you have to go through the trouble of debugging it. It's also used very often for forwards to make sure that values of arrays/strings, which are always passed in by reference, aren't changed by any plugins when they're not meant to.

Unfortunately, using const outside of function parameters doesn't work anymore in new syntax.

It didn’t work before either, it was just silently dropped.
