Hey Nokuthula!

So it looks like you got past the first part of the challenge, so you should be somewhere around here: 

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

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

Which outputs "population", "longitude", "latitude", and "country" to the console. Now to access the values associated with each of those properties, you'll either need to use dot or bracket notation for each property. So for dot notation: shanghai.property, or for bracket notation: shanghai[property].

So if you wanted to output to the screen the property, followed by a colon, followed by a space, and finally followed by the property's value, you'd want to do something like this (shown in dot notation):

for(var property in shanghai){
 console.log(property + ": " + shanghai.property); 
}

Hope that helps!
