AS3 Tween a variable inside an array

I have the following code which works perfectly:

    updaterVariable = 0;
    Tweener.addTween(this, {time:2, transition:"linear", updaterVariable:1000, onUpdate:tweenerUpdate});

I will get the value of updaterVariable tweened from 0 to 1000 in 2 seconds. My question is whether there is a similar way to tween a variable in an array, for example:

    updaterVariable[10] = 0;
    Tweener.addTween(this, {time:2, transition:"linear", updaterVariable[10]:1000, onUpdate:tweenerUpdate});

I tried the above code, and its not working. Can anyone help?

You can pass your array to the tweener and use index as a field to be changed:

updaterVariable[10] = 0;
Tweener.addTween(updaterVariable, {time:2, transition:"linear", '10':1000, onUpdate:tweenerUpdate});

Not sure which tweener you are using, however it works with TweenMax:

private var arr:Array;
public function Main() {
    arr = [];
    arr.push(0);
    arr.push(0);
    arr.push(t);
    TweenMax.to(arr, 1000, { '2' : 1000 } );
    addEventListener(Event.ENTER_FRAME, onframe);
}
private function onframe(e:Event):void {
    trace(arr[2]);//outputs expected numbers
}
