Tell us what’s happening:

I don’t understand what’s wrong with this code. I’ve tried editing the return strings without luck.

Your code so far

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";
  } else if (score >= 60) {
    return "D";
  } else {
    return "F";
  }
}

function hasPassingGrade(score) {
  return getGrade(score) !== "F";
}

function studentMsg(totalScores, studentScore) {
const classAverage = getAverage(totalScores);
const studentGrade = getGrade(studentScore);
const hasPassingGrade = studentScore > 59;
if (hasPassingGrade) {
  return "Class average: " + classAverage + "." + " Your grade: " + studentGrade + ". You passed the course";
}
else {
  return "Class average: " + classAverage + "." + " Your grade: " + studentGrade + ". You failed the course";
}



}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Hi there! The above line of code is unnecessary.

Above you need to call the function with an argument, not only reference it.

3

I can’t make the function call work.

4

Example of calling a function:

myFunc(arg)

Edit: You need to add one of your studentMsg function’s argument.

5

Yes I know that. What I meant is that I’ve tried passing pretty much all the variables in the function because I can’t figure out which one I need to use. None of them work.

6

Do you did that modifications to your code as I suggested?
Post your code

7

your code is fine you are just missing a . at the end of your output messages
