you have the loop for what reason? you never use i, and you just do that calculation. Also right now sum is 0, you need to calculate it to have a proper average

Step 1:
Use the for loop to iterate through the scores array and calculate the sum of its items.

Step 2:
Outside of the for loop, calculate the average by using the statement you wrote:

average = sum/scores.length;

Remember to declare average first.

Step 3:
return the average value.

function getAverage(scores) {

let scores = 0;

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

sum+=scores[i];}

}

you have an issue, the function parameter is scores, then you create a variable scores losing access to the function parameter

do not use the name scores for this variable
