Tell us what’s happening:

I have found a solution for this exercise that generates the expected result as seen on the website CONSOLE. However it returns an error. Can anyone, please give me insight on this solution? Thank you in advance for your help.

Your code so far


// User Editable Region

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

do you see two undefined on the console? that’s what these print because it’s what your function returns. You need to return the value from your function, not print it.

also, the console.log here is never reached because the return executes first, it stops the function, but it doesn’t determine an output, so the output is undefined

Thank you, I overlooked “return” is within the loop.
