Tell us what’s happening:

I don’t what is wrong with my code. I can’t pass.

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) {
  let grade = getGrade(studentScore);
  let average = getAverage(totalScores);
  let flag = hasPassingGrade(grade);
  
  if(flag){
    console.log("Class average: "+ average +". Your grade: " + grade + ". You passed the course.")
  }else{
    console.log("Class average: "+ average +". Your grade: " + grade + ". You failed the course.")
  }
  
  
  
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

1. The function should return the value.

2. hasPassingGrade takes a score which is a number, it then calls getGrade passing it the number and getGrade returns a string, that is compared against the string "F" and returns a boolean true or false. You can not pass a grade string to hasPassingGrade, you must pass it the studentScore which is a number, not a string.

I give the hasPassingGrade(studentScore) now.
But it won’t pass this test either.

Please share your udpated code

[liuyang3728]

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 grade = getGrade(studentScore);
  let average = getAverage(totalScores);
  let flag = hasPassingGrade(studentScore);
  
  if(flag){
    console.log("Class average: "+ average +". Your grade: " + grade + ". You passed the course.")
  }else{
    console.log("Class average: "+ average +". Your grade: " + grade + ". You failed the course.")
  }
  
  
  
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Your studentMsg function still doesn’t return anything

The function should return a string representing a message to the student.
