In the getStudentReport function, is there a purpose to the "student" parameter?

When he makes the function:

function getStudentReport(student)

Is there a purpose for the "student" parameter? It's not accessing the "student" variable from inside the For loop (student = students[i]), is it?

If it doesn't serve a purpose, why not just leave the function parentheses blank? Why type "student" in there at all? Thank you!

Your question has to do with scope.

If the getStudentReport function runs w/o the parameter, what would student.name print? What would students[i].name print if you put that in the function? Nothing because the object array of students and the object student are outside the scope of the function. You must hand the function the data it needs by way of parameter.
