You can include all the necessary code in one console.log statement

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

Seems to work on my end. Maybe using commas in the console.log statement is what it's asking for.

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

Hi Maxwell,

You don't need to explicitly print them with 4 console logs.

You use the for each loop to print one statement that loops through each of the properties in your shanghai object.

By referencing the key in the foreach loop using an array literal your single console.log will display all the values to console.

As below. Give it a go and good luck. :-)

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

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

thanks, what about : logging out the property names, include the property values too. In other words you want to log out 4 lines that include both the property name and value. For example: "population: 14.35e6"
