Tell us what’s happening:

I don’t understand why I am getting an error while I’m getting the error.

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) {
  let average = getAverage(totalScores);
  let grade = getGrade(studentScore);

  if (hasPassingGrade(studentScore)){
    return `Class average: ${average}.  Your grade: ${grade}. You passed the course.`; 
  } else{
    return `Class average: ${average}.  Your grade: ${grade}. You failed the course.`; 
  }

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

What error?

Here are some troubleshooting steps you can follow. Focus on one test at a time:

  • What is the requirement of the first failing test?
  • Check the related User Story and ensure it’s followed precisely.
  • What line of code implements this?
  • What is the result of the code and does it match the requirement? (Write the value of a variable to the console at that point in the code if needed.)
  • Are there any errors or messages in the console?

If this does not help you solve the problem, please reply with answers to these questions.

You have a spacing issue in your message. It should exactly match the expected output.
