The "toUpperCase()" method is not needed (and is invalid syntax) for the assignment:

newYork.country = 'USA';
Udayakumar T
Udayakumar T

Udayakumar T
Udayakumar T

you can try this

newYork.country = 'usa'; newYork.country = newYork.country.toUpperCase();

you can't directly assign a value with uppercase function, it needs to be assigned to some variables.
