Understanding colon purpose in hw.js

[Dave]

I'm trying to learn more about javascript and jquery in hppg but am
stuck on something simple. Where does the colon in the line of code
below originate from?

vote : function (photo,score)

How come it's not "function vote(photo,score)" or something similar?
I've had a good search for other examples of jquery/javascript using
similar expressions but can't find anything. Any pointers really
appreciated.

It's function of variable hw. That's why sintax is like this. Variable
is defined here:
http://code.google.com/p/hppg/source/browse/trunk/design/defaulttheme/js/hw.js#6

So that why I define function for hw variable. And it becomes
hw.vote() and is available during page lifetime.

I see, that helps my understanding, thanks.
