In JavaScript you can use ++ operator before (pre-increment) or after the variable name (post-increment). What, if any, are the differences between these ways of incrementing a variable?

I'm currently learning C++ and I've learned about the incrementation a while ago.
I know that you can use "++x" to make the incrementation before and "x++" to do it after.
Still, I really don't kn...

Half jokingly half serious : Why can't I do ++i++ in C-like languages, specifically in C#?
I'd expect it to increment the value, use that in my expression, then increment again.
