JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects Accessing All of the Properties in an Object

Getting an error on the code challenge.

Here is the challenge instruction below.

Use a for in loop to log each of the property names of the shanghai object to the console.

Here is my code.

script.js 
var shanghai = {
  population: 14.35e6,
  longitude: '31.2000 N',
  latitude: '121.5000 E',
  country: 'CHN'
};

for (var key in shanghai) {
  counsole.log(key);
};
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

So I ended up adding spaces in my "for in" loop and it accepted it for task one. Task 2 then ask me to "Now that you are logging out the property names, include the property values too. In other words you want to log out 4 lines that include both the property name and value. For example: "population: 1435e6""

<p>
var shanghai = {
  population: 14.35e6,
  longitude: '31.2000 N',
  latitude: '121.5000 E',
  country: 'CHN'
};

for ( var key in shanghai ) {
  console.log( shanghai [ key ] );
};
</p>

Here is the error message I get from this code "Oops! It looks like Task 1 is no longer passing."

Hi.

Seems you have a typo there:

var shanghai = {
  population: 14.35e6,
  longitude: '31.2000 N',
  latitude: '121.5000 E',
  country: 'CHN'
};

for (var key in shanghai) {
  counsole.log(key);  //should be console.log(key);
};

Regards,

var shanghai = { population: 14.35e6, longitude: '31.2000 N', latitude: '121.5000 E', country: 'CHN' }; for (var prop in shanghai){ console.log(prop + ": " + shanghai[prop]); }

console output:

population: 14350000 longitude: 31.2000 N latitude: 121.5000 E country: CHN

Hi Ira.

Sorry for the late reply.

console.log(key[shanghai]);

This is the solution :)

You were close :)

Enjoy your day and Happy Coding!
