What is being passed to the person argument?

I understand that promises return the resolved values, but what is being passed through the person argument? like in person.craft? or is it that the person is a part of the JSON object passed through?

The map method calls the supplied function once for each element of the object it is used on. So in this case, the person parameter will be one of the items from peopleJSON.people that was created on the previous line.
