please am stocked here
function getAverage(scores) {
let sum = 0;

for (const score of scores) {
sum += score;
}

return sum / scores.length;
}

function getGrade(score) {
if (score === 100) {
return “A++”;
} else if (score >= 90) {
return “A”;
} else if (score >= 80) {
return “B”;
} else if (score >= 70) {
return “C”;

Look at the parameters that are passed to your function. You need to use those as variables within your function.

You never define grade or average, so you cannot use those.

3

You have done following mistakes:

  • First, the double quotes are not consitent. You are using “ which is throwing a syntax error. Use simple double quotes ".
  • Second, the variables grade and average are not defined. You have to use the functions getGrade and getAverage to calculate the grade and average. So replace all the grade and average variables with those functions, and don’t forget to use resppective arguments.
