1. function clone(obj) {
   var o;
   if (typeof obj == "object") {
   if (obj === null) {
   o = null;
   } else {
   if (obj instanceof Array) {
   o = [];
   for (var i = 0, len = obj.length; i < len; i++) {
   o.push(clone(obj[i]));
   }
   } else {
   o = {};
   for (var j in obj) {
   o[j] = clone(obj[j]);
   }
   }
   }
   } else {
   o = obj;
   }
   return o;
   }
