Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

The output is correct but still gives error, tried everything but doesn’t work. Also tried template literals but didn’t work. Tried putting the message in a variable and then passing it to the return statement, didn’t work.

Your code so far

```javascript
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) {
  if (hasPassingGrade == true){
    return 'Class average: ' + getAverage(totalScores) + '. Your grade: ' + getGrade(studentScore) + '. You passed this 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));

Error:

// running tests
Your function call of studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100) should return the following message: "Class average: 50.8. Your grade: A++. You passed the course.".
Your studentMsg function should return the correct message based on the student's score and the class average.
// tests completed
// console output
Class average: 71.7. Your grade: F. You failed the course.

After this error, I also tried giving the “studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100)” as an argument in console.log but the error persists saying it doesn’t match.

Hi there!

Use function call. Not the reference.

function studentMsg(totalScores, studentScore) {
  if (hasPassingGrade(studentScore) == true){
    return 'Class average: ' + getAverage(totalScores) + '. Your grade: ' + getGrade(studentScore) + '. You passed this 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));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Gives the following output:

// running tests 
Your function call of studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100) should return the following message:
"Class average: 50.8. Your grade: A++. You passed the course.". Your studentMsg function should return the correct message based on the student's score and the class average. 
// tests completed 
// console output 
Class average: 71.7. Your grade: F. You failed the course.
Class average: 50.8. Your grade: A++. You passed this course.

remove that equality opretor and boolen true, hasPassingGrade(studentScore) is already checking the truthness.
Edit:

also correct the text of that string. you need to write the , instead of this.
that is the main problem.
