[Javascript] Array limits?

[Pitre, Russell]

Is there a limit to the width of javascript array?

i.e.   

function item(item, qty, text, institution, logo, colors, size, picURL,
size, innerHTML, displaySize){
	this.item;
	this.qty;
	.
	.
	....
}

The width is 11.  I can use a test alert to display all values, but the
"displaySize".....
