Tell us what’s happening:

So, this is my first time trying this out and I’m not getting it right. Is there a problem with my loop?

Your code so far


// User Editable Region

function getAverage(scores) {
let length = getAverage.length;
let sum = 0;
let average = scores.sum/scores.legth;

for (let i = 0; i < scores.length; i++){
  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]));

you have a typo

what do you want to do here?

finally, you don’t have a return statement

Tell us what’s happening:

I have tried all this but still having issues, please is there something wrong with mu loop?

Your code so far


// User Editable Region

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

take a closer look at your return statement.
here’s your code indented properly so you can read it better:


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

Is your return in the correct place? How about your let average... line?
