The newYork variable contains an object, but the population is wrong. Add a line of code that sets the population proper

it keeps saying error

script.js 
var newYork = {
  population: 100, 
  latitude: '40.7127 N',
  longitude: '74.0059 W'
};

var population

population.shift=('8.406e6');
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

To change the value of a property, you can use dot notation to access the property and then assign the new population value like this:

newYork.population = 8.406e6;

Hi Eukael,

The way you assign a new property to a key, is by referencing the variable followed by the key. I.e:

var newYork = {
  population: 100, 
  latitude: '40.7127 N',
  longitude: '74.0059 W'
};

newYork.population = 8.406e6;
