You're so close but the challenge wants you to use the var keyword. You want something like this

var shanghai = {
  population: 14.35e6,
  longitude: '31.2000 N',
  latitude: '121.5000 E',
  country: 'CHN'
};

for(var key in shanghai) {
  console.log(key + shanghai[key]);// you want to concatenate var key and shanghai object then pass the key variable inside the shanghai object
}
