easy to understand function to delete duplicated elements in an array

	function deleteDuplicates(arr) {
	arr.sort();
	var lastElement = '';
	var arrDuplicate = arr;
	for (var i = arrDuplicate.length; i >= 0; i--) {
	if (arrDuplicate[i] == lastElement) {
	arr.splice(i, 1);
	}
	lastElement = arrDuplicate[i];
	}
