Function to create new array

1

Here’s what I’d like to do.
Call a function that looks at an existing array and creates a new array.
I don’t want to copy the existing array, but I want to use its length, to populate the new array. I want to be able to name the new array in my function declaration (possible?).
The prefix parameter is used to push existing variables into the new array.


function createNewArray(oldArray:Array, newArray:Array, prefix:String):void {
	var arrlength:uint = oldArray.length;
	//
	for (var i:uint = 0; i<arrlength; i++) {
		newArray.push(this[prefix+i]);
	}
}
var answer_0:String = "no no no"; 
var answer_1:String = "blah blah blah"; 
var answer_2:String = "yeah ok"; 
// var answers:Array = new Array();

createNewArray(questions, answers, "answer_");

declaring the new Array before calling the function works, I was just wondering if it was possible to skip this step, in order to make the function call/array creation more dynamic.
