dd a new property -- country -- to newYork. Don't change the original object, just add this new property using a = sign

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

};
newYork.population = 8.406e6

Same way as the one you just did, just add a period and assign the value with an equals sign.

newYork.population = 8.406e6;
newYork.country = 'USA';

Great job solving the first task! :thumbsup: To add a new property, you could do this: (This won't work in the challenge; it is for showing you how you could solve the challenge)

var person = {
    name: "Raeed Sabree",
    age: 30,
};

// ADDING A NEW PROPERTY EXAMPLE
person.eyeColor = "brown";

Hope this gives you an idea of how you could solve the task! :dizzy:
