I have a JSON function that works fine but I want to know how to display all of the results without using a for loop my code is below:

Code:
function newarticlescallback(rtndata) 
{ 
	$('#pagetitle').html("New Articles");
	var data="";
	for(var j=0;j<9;j++)
	{
 
         data = data + "<li><a href='#' onclick=\"History.pushState({state:null},'article,"+rtndata[j].id+"','article'); return false;\">" + rtndata[j].title + "</a></li>";
	
	}
	$('#testing').html(data);
}
