7,865 PointsI didnt think the key name mattered but I am getting an error that strict mode does not allow this name
I have tried doing it just like the practice problem, but it is not working
var shanghai = {
population: 14.35e6,
longitude: '31.2000 N',
latitude: '121.5000 E',
country: 'CHN'
};
for(property in shanghai){
console.log(property);
}

for (let property in shanghai) { // you could also use "var"
Strict mode does not allow implicit global declarations.
