How can I alter the way Array data displays?

Question

I can trace the Array data and I get each array item
separated by a comma. How can I replace that comma with a dash so I
show "Index0 - index1 - index2" instead of "Index0, index1, index2"
Thanks!

var myArray:Array = new Array("item1", "item2", "item3");
var reg:RegExp = /,/g;
var arString:String = myArray.toString();
var newString:String = arString.replace(reg, " - ");
trace(newString);
