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!
