So if we create a function and add a variable to the global scope then we can call it using this

Ok, cool, I am a zen master as I start to fix, approaching both my thinking and the project from several different angles. I spend 5 hours methodically working my way through this code and ultimately get nowhere. By this time I’m frustrated enough to go ask a technical mentor for help.
