Front End Web Development Techdegree Graduate 84,698 PointsThey want you to print out just the property
, also you need to use either the var
keyword when declaring that local variable at the beginning of the loop:
for (var property in shanghai ) {
console.log(property);
}
FYI, if they wanted you to print out the property value instead if the property name, you could do that with shanghai[property]
; property[shanghai]
is going to break. shanghai
is the object and you access properties either with dot notation or bracket notation with the key name.
