Tell us what’s happening:

Hi, I’m new here. I need help with this Part, the console returns the Average and Grade of the Student, but I still get an error in the Console, why is that? Could you help me with an hint?

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";
}


// User Editable Region

function studentMsg(totalScores, studentScore) {
  hasPassingGrade();

  if (hasPassingGrade === true) {
    return "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + ". You passed the course."
  } else {
    return "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + ". You failed the course."
  }
}

console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Hi there!

Remove the floating function call hasPassingGrade(). Call the function within the if condition and pass the studentScore as an argument to it.
