a use case from MDN

You can use obj.constructor.name to check the "class" of an object

function a(){
}

var b = new a();
alert(b.constructor.name); //Alerts "a"

Think of it the as using get_class() in PHP or .getClass().getName() in Java.

I can only imagine you might want to use it in eval type situations.
