Javascript HashTable use Object key

Question

I want to create a hash table with Object keys that are not converted into String.

Some thing like this:

var object1 = new Object();
var o         


        

Answer 1

I took @Ilya_Gazman solution and improved it by setting '_hashtableUniqueId' as a not enumerable property (it won't appear in JSON requests neither will be listed in for loops). Also removed UniqueId object, since it is enough using only HastTable function closure. For usage details please see Ilya_Gazman post

function HashTable() {
   var hash = new Object();

   return {
       put: function (key, value) {
           if(!HashTable.uid){
               HashTable.uid = 0;
           }
           if (typeof key === "string") {
               hash[key] = value;
           } else {
               if (key._hashtableUniqueId === undefined) {
                   Object.defineProperty(key, '_hashtableUniqueId', {
                       enumerable: false,
                       value: HashTable.uid++
                   });
               }
               hash[key._hashtableUniqueId] = value;
           }
       },
       get: function (key) {
           if (typeof key === "string") {
               return hash[key];
           }
           if (key._hashtableUniqueId === undefined) {
               return undefined;
           }
           return hash[key._hashtableUniqueId];
       }
   };
}
