Tell us what’s happening:

function studentMsg(totalScores, studentScore) {
if (hasPassingGrade(studentScore)) {
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([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37);
what mistake in my code i am getting 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) {
if (hasPassingGrade(studentScore)) {
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([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37);

Copy-pasting the code doesn’t tell me what about your code has you stuck. Con you try talking about your code and what you’ve tried to fix it?

Here, you did something wrong with the console.log statement.
You wrote “console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37);”
This is incorrect.
Essentially, you forgot to add a parenthesis for the function inside the console.log statement.
Happy coding!
