I don't know what this question is asking for

'Now that you are 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"'

This is the JS I tried ...

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

for (var key in shanghai) {
  console.log(key) + ': ' + console.log(shanghai[key]);
<!DOCTYPE html>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
<script src="script.js"></script>

You almost got it right, you are adding an extra console.log statement:

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

Here you simply built the string to be output to the console. Cheers.

Right. Thanks. I guess my brain's tired.

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]); }
