hello. remember the way to add keys and values to objetcs

object.keyName = value;

// in this case newYork is the object, 

population: 100, 
// polutation   is the key
// 100   is the value

how would you add another key and value to this object?

newYork.key = 'value';

i hope this makes senses

It looks like you're on task 2, but the first task was "Add a line of code that sets the population property to 8.406e6. Don't change the original declaration of the object."

Remember the warning in the instructions: "Important: In each task of this code challenge, the code you write should be added to the code from the previous task.", so the code you added to pass task 1 should be left as is when you work on task 2.

Then for task 2, it says: "Don't change the original object..." but the code above shows "country" added to the original object. Instead, write a line of code to add it using an assgnment as the instructions asked: "just add this new property using a = sign".

this is how the code from task 1 looks like and it let me pass: var newYork = { population: 100, population: 8.406e6, latitude: '40.7127 N', longitude: '74.0059 W'

}; however now, I still dont get how should I enter the country

I guess the checker wasn't being very thorough. Remember the instructions say "Don't change the original declaration of the object."

Both the new population and the country should be added after the object using assigments ("=").
