Help!!!!!! what is the answer for this one and why? what does the length mean here to get a total score?

Hi Hanwen!

No, the question is:

Complete the code below to assign the totalScores variable THE NUMBER OF ELEMENTS in the scores array:

So you are just storing how many scores there are, not totalling them (in this case).

I hope that helps.

Stay safe and happy coding!
