Tell us what’s happening:

there is something wrong of the code
I think it isn’t my fault
let sum=0
function getAverage(scores) {
for(let i=0;i<scores.length;i++){
sum+=scores[i]

}
return 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]));

the result is 1=71.7
and the second one is=85.4

Your code so far

This right here is a bug in your code. What happens to the sum if you try to run your function twice? Why is that sum variable hanging out there outside of your function?
