JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects Access and Set Object Properties

Seeking help

I've been having difficulties passing this task for a few hours, I watch the videos and still confuse on the tasks. On task 1 it tells me to not change anything in the object, so I created a second "population" and place the value in it and passed it but its not the "correct" way of doing it, so for task 2 It tells me to put country and a = sign to USA nothing else and I did but says tasks 1 is not passing now, can someone break it down for me on how to complete this tasks?

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

};

Without giving a spoiler, here's a generic example. Let's say you had an object named "person" that had properties for "name" and "age":

var person = {
    name = "Joe",
    age = 24
};

Now, without changing the original definition, let's update this person's age to be 25:

person.age = 25;

Then we want to give the person a new property which is their brand of car:

person.car = "Honda";

Make sense now?

Ok it making sense now, so I put “newYork.population = 8.406e6” even though it says error still it’s the correct set up. So is it because I’m missing something small?

When I paste that line in to task 1, it passes. Are you still having trouble?

newYork.population = 8.406e6;
