What is 'arr'?

What is the purpose and point of arr? I know it's a parameter but what part of the overall code is 'arr' linked to?

It is just an input parameter for the function, it is because you are passing in an array, looping through it then returning a string which joins together the different parts of the array. Does that answer your question?

ehhh. still confusing to me. thanks for you effort. can you word a little differently, please? Also, when you say array and when Dave saids array, are you guys referring to the "var correct" and "var wrong" array?

Whatever you will pass to a function are the parameters of a function and they can be named anything. In this case, "arr", which is also worded to hint that you'll pass in an array. Correct, you are passing in the arrays "correct" and "wrong" which you will create a list for each of them.
