Full Stack JavaScript Techdegree Student 2,690 PointsJavaScript Loops, Arrays, and Objects - For In Loop Challenge Task 1 of 2
This challenge's instructions are "Use a for in loop to log each of the property names of the shanghai object to the console."
My code was:
var shanghai = {
population: 14.35e6,
longitude: '31.2000 N',
latitude: '121.5000 E',
country: 'CHN'
};
for (prop in shanghai) {
console.log(prop, ': ', shanghai[prop]);
}
and I received this error code:
"There was an error with your code: ReferenceError: Strict mode forbids implicit creation of global property 'prop'."
What am I missing here? Thanks in advance for your help.

for (var prop in shanghai) { console.log(prop);
}
