Tell us what’s happening:

Hi, I am very lost on where to start. Please help.

Your code so far


// User Editable Region

function getAverage(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]));

You can think of this as a math problem. To calculate the average score, add all the numbers in the array and divide the sum by the length of the array.

Hope this helps you get started!

That was helpful, thanks. But, I am still a bit confused as to why my code is not passing still.

My hint says:

Your getAverage function should return a number.

My console says:

And this is my code:

function getAverage(scores) {
  let sum = 0;
  console.log(scores);
  for(let i=0;i < scores.length;i++){
    sum= sum + scores[i];
  }
  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]));
console.log(getAverage([38, 99, 87, 100, 100, 100, 100, 100, 100, 100]));

Any help will be much appreciated. Thank you.

do you remember how you return a value from a function? it is a different thing than printing to the console

Where did you start? I understand the task mathematically, but am not quite sure how to put it in JS.
