Global Variable.
I see that we need to declare the variable "i" in the for loop using the keyword "var". example for ( var i = 0 ; i <scores.length ; i++)
As I have learned in the previous lessons that if I don't declare a variable inside a function it becomes a global variable. What if I don't write var in front of i? Does that make it a global variable??
Yes, it does!
