Hi Sandy,

You've accidentally placed your for loop inside the shanghai object creating a syntax error and you're also missing a closing curly brace.

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

// place your for in loop here after the closing of the shanghai object

Also, you'll get a message suggesting it's a good idea to use the var keyword for your prop variable.

Example: for (var prop in shanghai) {

I don't know about you but I have had to restudy core concepts in JavaScript. YouTube provides many JavaScript videos

for Functions, Closures, Variables and the like. Having another teacher's perspective has been invaluable for me,

Struggling as I am. (Hope this helps)
