So how do you do this then?

Question

So the second part of the challenge in Access and Set Object Properties portion of the Loops, Arrays and Objects bit in the Javascript Track, says this:
Challenge Task 2 of 2
Add a new property -- country -- to newYork. Don't change the original object, just add this new property using a = sign to assign the country property to USA.
Here was the existing code:
```javascript
var newYork = {
  population: 100, 
  latitude: '40.7127 N',
  longitude: '74.0059 W'
  country: 'USA' //I added this bit here, which is actually incorrect
};
population = 8.406e6; //This was from the 1st task
```
I eventually got past the challenge by just changing the original object literal, but as that was actually the opposite of what the challenge asked, how exactly do you add a property to an existing object?
I tried both 
javascript
newYork['country'] = 'USA';

and
javascript
newYork.country = 'USA';

but neither seemed to work... :/

Hey Denise,
Both 
javascript
newYork['country'] = 'USA';

and 
javascript
newYork.country = 'USA';

will let you add properties to the newYork object. For this challenge, the code should look something like this:
```javascript
var newYork = {
  population: 100, 
  latitude: '40.7127 N',
  longitude: '74.0059 W'
};
newYork.population = 8.406e6; // First Task: change value of existing property
newYork.country = 'USA'; // Second Task: add new property to object
```
Alternatively you can also use this:
```javascript
var newYork = {
  population: 100, 
  latitude: '40.7127 N',
  longitude: '74.0059 W'
};
newYork['population'] = 8.406e6; // First Task: change value of existing property
newYork['country'] = 'USA'; // Second Task: add new property to object
```

Hmm, I guess it must have been a glitch why it didn't work. Well, at least I know I wasn't missing anything. Thanks, Huy!
