Tell us what’s happening:

Hey, it keeps saying my getAverage function should have a return value, I already looked at other post and the “How to add numbers in a javascript array” link, but no matter how I arrange it, it keeps saying my code doesn’t pass. Am I missing something?

Your code so far


// User Editable Region

function getAverage(scores) {
  let sum = 0;
  for (let i = 0, i < scores.length, i++){
  scores += scores.length;
  }
  return average = sum of all scores/total number of scores;
}

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]));

this is a syntax error all on its own

scores is an array, if you do this it’s not an array anymore. You should add to sum instead, and add the elements of scores (accessed with bracket notation` to it
