Your code so far


// User Editable Region

let scores = [92, 88, 12, 77, 57, 100, 67, 38, 97, 89];
let score = [45, 87, 98, 100, 86, 94, 67, 88, 94, 95];
function getAverage(scores) {
sum = 0;
for (i = 0; i < scores.length; i++) {
sum += scores[i];


  }
let average = 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]));

2

You are not declaring your variables. Also, you need to return the average from the function.

3

Where did you find the instructions for these two lines?

The variable is not declared

The result should be returned.

4

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

console.log(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]));

5

pls check, it is still not working

6

You don’t need the ‘average’ variable, return what you have from the right side of the equality operator (without the equality operator, of course).

You don’t need this statement.

7

You should declare the loop variable, too.
