So you're looking at the array. And you want to know how long it is. This is a property of the array. You can find the answer here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array

The question ask you to to store the number of items in the array scores into the variable totalScores. You will use the length It should be 

var totalScores = scores.length ;
