When I test this code in workspace it is logging all the property names in the object to the console, but not passing.

The code is working outside of this test, so I may be understanding the instructions incorrectly. When tested I get:

population longitude latitude country

all logged to the console.

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

for (prop in shanghai) {
  console.log(prop);
}

I copy/pasted your code and received: Bummer: It's a good idea to use the var keyword in a for in loop like this: `for (var key in shanghai). Doing as the error suggests passed task 1.

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

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