quiz auto error

having trouble with a quiz for JS loops arrays and objects- error message is "bummer: its a good idea to use a var keyword such as 'var key in shanghai' <<< the problem is thats what I am doing and have in in the workspace. Ive tried to reset and try again but the same error appears.

var shanghai = { population: 14, longitude: 31, country: 'CHN' };

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

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

again, error suggests that I use var keyword (??) and Im unable to clear it by resetting the exercise

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]); 
};

I think the issue is that you have two separate loops. This is one of the few challenges where you are asked to modify the code you created for the first task instead of creating completely new code for the second task.

Great. Then I have some suggestions about this workspace to improve the experience for learners like me.
