In JavaScript, you can do this:

var a = null;
var b = "I'm a value";
var c = null;
var result = a || b || c;

And 'result' will get the value of 'b' because JavaScript short-circuits the 'or' operator.

I don't think that code metrics (sometimes referred to as [software metrics](http://en.wikipedia.org/wiki/Software_metric)) provide valuable data in terms of where you can improve.
With code metrics it is sort of nice to see how much code you write in an hour etc., but beyond they tell you nada ab... | [
