I am trying to make 2d array in javascript but this error keep on coming "Type 'Object' does not support slicing". Can anyone help please.

var i:int = 0;
function Start ()
{

	var myarray=new Array(4);
	var array1=new Array(4);
	array1[0]="Apple";
	array1[1]="Pear";
	array1[2]="Banana";
	array1[3]="Orange";
    
	for(i =0; i<array1.length;i++) 
	{
		 myarray *= new Array(2);*

_ myarray[0][0]= array1*;_
_ myarray[0][1]= array1;
}
}*_

A 2D array is declared and used like:

var myArray = new String[4, 2];
myArray[0, 0] = "Apple";
