OR operator between javascript functions

Question

I am debugging a complex javascript and I came across a line:

 (this.kq.hu || nq.hq)(uu);

hu and hq are both functions and uu is a variable(if Im correct)

I tried to find out what this line of code does for the past hour with no luck.

Does anybody know what exactly this line of code does?

I think this is something very small.. but I do not get it after giving it a thought.

You can find the full js here: http://pastebin.com/n6rXT7sf

Its line# 35

It's the equivalent of this:

if (this.kq.hu) {
  this.kq.hu(uu);
} else {
  nq.hq(uu);
}

Translated: if this.kq.hu exists, call it with parameter uu, otherwise call nq.nq with the same parameter.

if (this.kq.hu === null || this.kq.hu === undefined) function nq.hq will run, else this.kq.hu will run with parameter uu.
