Changing the values of each object property using a for in loop?

I am wondering what I would have to put into the body of a for in loop

for (var prop in spy) {

};

in order to change the value for each key to a string?

:point_right: The keys are strings, no conversion necessary.

But if you meant you wanted to change the property value to a string: spy[prop].toString()

I did end up finding the answer! I wanted to change each property value in the loop to a specific string, eventually I found the answer! It was almost the exact code you used! Thanks for the help!
