Looks like you have a trailing comma after the closing bracket for the console.log()

Your updated code would be:

for (var key in shanghai) { console.log(key, ': ', shanghai[key]) };

Looks like you almost have it. The second for loop becomes redundant if you just update the console.log in the original fore loop to output the ': ' string and the value of shanghai[prop]

For example:

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

for (var prop in shanghai) { 
    console.log(prop, ': ', shanghai[prop]);
};
