Hello there.
This is not the correct way to loop through items. Use a for loop.
In the loop, you are getting the numbers of items in the scores parameter, why do you have the getAverage function?

To access the elements of the array, you should use scores instead of the getAverage function here

Also, declare the sum variable inside the function, that way, it’ll be limited to that scope .Declaring it outside will give it a global scope This also means you should delete the console log cause it will lead to a reference error since the sum is not declared within its scope.
