JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects Accessing All of the Properties in an Object

Code for 'for in' to loop through an object's properties is not working!

It looks good to me, but says that "task 1 is not longer passing."

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

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


for(var key in shanghai) {
  console.log(key,':', shanghai[key]);
}
index.html 
<!DOCTYPE html>

  <meta charset="utf-8">

<body>
<script src="script.js"></script>
</body>
</html>

Hi Ronan,

This challenge wants you to upgrade the console.log you're using to log out the key and then the value at that key, as well. You need to use the same for in loop you created because it tells you to include the value as well as the key. 

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]);
}
