what need how can change the style of object way of changing

   { 201:{9:"alfreds futterkiste",10:"berlin"}, 204:{9:"vaffeljernet",10:"Århus"} }  

here's plunker(just js) :http://plnkr.co/edit/h3endn8f6milhf2h1gaj?p=preview

 var array =    [       {         9 : "alfreds futterkiste",         10 : "berlin",         room : "201"       },       {         9 : "vaffeljernet",         10: "Århus",         room : "204"       }     ];    var result = {};    array.foreach(function(obj) {     //function runs once each element in array, obj = element @ current index     result[obj.room] = {       9: obj[9],       10: obj[10]     };     });    console.log(result); 

the basics are: [] array; {} object. in arrays things identified index(0,1,2...). in objects have keys.

obj = {"201": {'key1':'value1', 'key2': 'value2'}} 

means have object inside have nested object (identified it's key - 201). nested object has 2 properties. first property has key(key1) , value (value1)

obj["201"] {'key1':'value1', 'key2': 'value2'} 

edit:

i suppose want more general solution

     var newobj ={};      object.keys(obj).foreach(function(key) {        if(key !== 'room') {          newobj[key] = obj[key];        }      });      result[obj.room] = newobj; 

see if can figure out put this
