Join function in knockout js observableArray?

Question

Is there a way to perform the javascript join function in a observableArray?

In javascript i can do the following:

var a = ["1", "2", "3"];

var p = a.join(',');

and p would be "1,2,3" but with knockout i cant found a way to do this action?

var x = ko.observableArray(["1", "2", "3"]);

var p = x().join(',');

Damn... sorry for the question... it was really dumb to not try the "()". – Phoenix_uy Jun 26 '13 at 14:45
