Declaring for Loops

I'm confused on why you have to put scoreCards[i].length instead of just scorecards.length

Well, scoreCards[i].length will return the length of just one of the scoreCards (the one with index "i"), while scoreCards.length would return the number of scoreCards in the collection instead.

If that doesn't answer the question, please identify the course, video, and time index you are referring to.
