Tell us what’s happening:

I never figured out the solution to this part of the lesson so I cheated by finding the answer online. After trying to understand how this solution works I was still very confused. If possible can someone please break down each part of this solution so I can solve similar questions in the future without cheating.

Your code so far

function getAverage(scores) {
let sum = 0;

  for (const score of scores) {
    sum += score;
  }

  return sum / scores.length;
}

console.log(getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89]));
console.log(getAverage([45, 87, 98, 100, 86, 94, 67, 88, 94, 95]));
