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

Inspired by @florian, here's a way where the id doesn't need JSON.stringify:

'use strict';

module.exports = HashTable;

function HashTable () {
  this.index = [];
  this.table = [];
}

HashTable.prototype = {

  constructor: HashTable,

  set: function (id, key, value) {
    var index = this.index.indexOf(id);
    if (index === -1) {
      index = this.index.length;
      this.index.push(id);
      this.table[index] = {};
    }
    this.table[index][key] = value;
  },

  get: function (id, key) {
    var index = this.index.indexOf(id);
    if (index === -1) {
      return undefined;
    }
    return this.table[index][key];
  }

};
