Sorry, your code does not pass. Hang in there.
Your getAverage function should return a number.

Your code so far


// User Editable Region

function getAverage(scores) {
  let lengthOfArray = scores.length;
  let totalOfAll= lengthOfArray*100;
  let sumOfAll = 0;
  let average = 0;
  let num = 0 ;
  
console.log(lengthOfArray);
  for(let i=1;i<=lengthOfArray;i++){
  num = scores.shift();
  sumOfAll = sumOfAll + num;
  }
   return sumOfAll/lengthOfArray;
   
}
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]));
console.log(average);

Hi and welcome to the community!
Why are you logging average to the console? If you notice, you’ve defined average inside the function and then using it outside the function which causes the error.
Good luck!
