Hey Raeed,

You access the properties of an object with a simple dot-notation:

var example = {
    age: 100
}

example.age = 10;

you have a population property in the newYork object already. To change a property in an object you target the object and property like this: object.property = newValue;

In your case you would target the newYork object's property 'population' and set the new value

newYork.population = 8.406e6;
