Tell us what’s happening:

function getAverage(scores) {
for (let i = 0; i < scores.length; i++) {
totalScore += scores[i];
return totalScore / scores.length;
}
}

how do I make my getAverage function return a number

Your code so far


// User Editable Region

function getAverage(scores) {
for (let i = 0; i < scores.length; i++) {
  totalScore += scores[i];
  return totalScore / scores.length;
}
}
getAverage();

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]));

It’ll only return a number when it knows what number that will be. Right now the browser doesn’t know what the value of totalScore is. As a result; it can’t perform any mathematical operations.

Define totalScore and your code will work.

Happy coding. :slight_smile:
