What is scope? Your explanation should include the idea of global vs. local scope.

SCOPE IS THE UMBRELLA OR ROOM WHERE THE JS INTERPRETER IS LOOKING FOR VARIABLES TO USE, THESE COULD BE
IN THE GLOBAL SCOPE WHICH COULD BE THE UMBRELLA FOR MANY FUNCTIONS IN MANY FILES OR IT COULD BE LOCAL, 
WHICH WOULD BE IN JUST A BLOCK OF INSTRUCTIONS FOR ONE FUNCTION

Why are global variables avoided?

THEY CAN BE HARD TO TRACK IF THERE'S ALOT OF SCRIPT TO SEARCH ON AND COULD CAUSE BUGS

// For each object from the original array, it should return the original name and course,
