I completed the assignment, but the system says that I'm not allowed to create a global property called "property".

I have to assign a name in a "for in" loop in order to call it in the console.log command. Is there a specific name I'm supposed to give it? Is my syntax flawed?

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

for ( property in shanghai) {
  console.log (property)
}
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

Your loop does indeed use improper syntax. Even in a loop definition, you still have to declare your variable with a keyword, either var, let, or const

"property" needs to be declared as a variable?
