Had a problem I came across, looping through a multidimensional associative array in JavaScript.

 var oldToNewMap = {   id1: { attrib1: "value1" },   id2: { attrib2: "value2" } };

//loop through mapping array  for (var id in oldToNewMap)  {   for (var attrib in oldToNewMap[id])   {                                var new = oldToNewMap[id][attrib];    whatever(id, attrib, new);   }  }
