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);

  // Get the student's grade using the getGrade function
  const studentGrade = getGrade(studentScore);

  // Check if the student passed or failed
  const passed = hasPassingGrade(studentScore);

  // Build and return the appropriate message
  if (passed) {
    return "Class average: " + classAverage.toFixed(1) + ". Your grade: " + studentGrade + ". You passed the course.";
  } else {
    return "Class average: " + classAverage.toFixed(1) + ". Your grade: " + studentGrade + ". You failed the course.";
  }
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
