After calling whosgotthefunc you get "Andrew" but then when you console.log(person) you would get Nick?

Because they are console.log person in the global scale, which is either "Jim" or "Nick" but the second person in the global scale (Nick) is just the original person with the value changed?

Ok, I believe your referring to the first question after the video. Because there is the keyword "var" in front of the variable name within the function "whosgotthefuc", the global variable "person" is not changed. If the word "var" wasn't there then the global variable "person" would change. Does that make sense?
