Tip #35 Elaborate on ++ and --

[ffigiel]

Sorry to bash on this tip like that, but I think we could provide more details on ++ and -- operators. Maybe add a new section about them?

For example, what's the difference between var b = --a; and var b = a--;?

[timomeh]

Seeing that post I immediately thought that, too.

Knowing the difference between a-- and --a is quite useful – especially in combination with ternary operators.

[hsleonis]

Yeah. a-- and --a or a++ and ++a are quite interesting.

var a = 3;
var b = --a; // Now b is 2

And

var a = 3;
var b = a--; // Now b is 3

@megapctr Could you create a new PR with the proposed changes? We'll merge once we review it.

Thanks.

[ffigiel]

You're welcome 😉

I noticed that jstips.co doesn't render my ordered list properly (compare to github). Should I open an issue for this?

[zenopopovici]

@loverajoel It seems that Jekyll is doing something fishy with the GitHub pages. Is this related to the warning we receive on each merge?

[loverajoel]

@zenopopovici @mebjas so strange, I think that maybe it's related with the Jekyll update in the last time for Github, I will back with more info.
Thanks
