dir = "asc" sortarray = new array("hello", "link google", "zfile", "afile");  //sort array if (dir == "asc") {     sortarray.sort(function(a, b) {         return a.tolowercase() > b.tolowercase()     }); } else {     sortarray.sort(function(a, b) {         return b.tolowercase() > a.tolowercase()     }); }      (var = 0; < sortarray.length; i++) {     console.log(sortarray[i]); }
