I’ve added a console.log() to your code.

It’s a crucial troubleshooting step to send your variables to the log so you can see what’s happening.

// User Editable Region

let result = 0;
function getAverage(scores=0) {
  for(let i= 0 ; i<10 ; i++){
    console.log("result",result)
  result = scores[i] + result;
  }
  return result/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]));
console.log(getAverage([38, 99, 87, 100, 100, 100, 100, 100, 100, 100]));
console.log(getAverage([38, 99, 87, 100]));
