Tell us what’s happening:

[JavaScript Gradebook Part 4]The code is displaying the correct message but it’s getting an error.

function studentMsg(scores, score) {
const classAverage = getAverage(scores);
const grade = getGrade(score);

if (score >= 50) {
return 'Class average: ’ +classAverage+ '. Your grade: ’ + grade + ‘. You passed the course.’;
}

else {
return 'Class average: ’ + classAverage + '. Your grade: ’ + grade + ‘. You failed the course.’;
}

}

What am I missing?

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";
}

This is not the correct condition I think. You have a function that you can use instead to check if the score is a passing one.

yes, I wrote if (hasPassingGrade(score) === true) instead and it worked, thanks.
