   "state": "TX",

	  return ( (A < B) ? -1 : ((A > B) ? 1 : 0) ) * [-1,1][+!!order];

}

// USAGE
// Sort by price low to high
homes.sort(sort_by('price', true, parseInt));
var u1 = document.getElementById('u1');
for (var i=0; i<homes.length; i++) {
	u1.innerHTML += '<li>- '+homes[i].price+', '+homes[i].city+'</li>';
}

// Sort by city, case-insensitive, Z-A
homes.sort(sort_by('city', false, function(a){return a.toUpperCase()}));	
var u2 = document.getElementById('u2');
for (i=0; i<homes.length; i++) {
	u2.innerHTML += '<li>- '+homes[i].city+', '+homes[i].price+'</li>';
