ECMAScript 5: No, its not possible with objects. You should either iterate with for..in, or Object.keys, like this for (var key in dictionary) { // check if the property/key is defined in the object itself, not in parent if (dictionary.hasOwnProperty(key)) { console.log(key, dictionary[key]); } } 이것저것해도 안되었는데 저걸로 하니 되었음 ㅎㅎ 오브젝트 형태는 Car : { hyun : 'h', kia:'k', carList : null } 누군가 도움이 되길..
