Tell us what’s happening:

please help me with this code i have tried submitting the challenge but it keeps telling me, the function should return a correct massage .

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) {
  // Calculate the average of totalScores
  const average = totalScores.reduce((acc, curr) => acc + curr, 0) / totalScores.length;
  
  // Determine the student's grade
  let grade;
  if (studentScore >= 90) {
    grade = "A++";
  } else if (studentScore >= 80) {
    grade = "A";
  } else if (studentScore >= 70) {
    grade = "B";
  } else if (studentScore >= 60) {
    grade = "C";
  } else if (studentScore >= 50) {
    grade = "D";
  } else {
    grade = "F";
  }
  
  // Create the result message
  const result = `Class average: ${average.toFixed(1)}. Your grade: ${grade}. ${
    grade === "F" ? "You failed the course." : "You passed the course."

// User Editable Region

  }`;
  
  return result;
}

// Example usage
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37)); // "Class average: 71.7. Your grade: F. You failed the course."
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100)); // "Class average: 50.8. Your grade: A++. You passed the course."

i suggest you rewrite this code because they wanted you to use the functions you already wrote to get the average and figure out whether the person passed or not.
