There might be a missing 'var' in the quiz.

At 'JavaScript Loops, Arrays, Objects" Object section's 12th part gives me below questions:

Given the following JavaScript code: 

var car = {
  make: "Ford",
  model: "Fiesta",
  year: 2015
}
for ( property in car ) {
  console.log( property );
}

Thank you for clarify it.

And the answer is no, because you are using property as a temporary variable that holds the values of the properties. In each iteration you are changing the value of property and printing it out.

I hope this helped. Let me know if not, I can try to come out with something different.
