The second part you need to get the key, this is done by the object name with square brackets for each property like so

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

for (var property in shanghai ) {
  console.log(property + ": " + shanghai[property]);
}

Hi Kim

You got the right idea but with the for loop but the variable you use is the looping through the properties.

So,

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

for (var property in shanghai ) {     // for the properties in shanghai object
  console.log(property);              // log each property
}

Good Luck

Hi Liam. The first part works fine. but the second part, nothing works unless i've got it out of line. i've tried doing all 4 lines of each property but it still isn't working. I just have this one last one left and nothing is working. I've tried everyone's suggestions.

thank you Liam. I need an actual teacher. I'm having a difficult time with retention of this.
