Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

Hi there guys! I’m hyped to make my first post and get into the Forum activity!
Been scratching my head over this one and looking up like crazy for a couple days:

I seem to do everything it asks me on the steps to the letter, but it keeps asking me for Step 3 to be completed.
The code is functional as it logs both outcomes properly, so I just don’t know which way else to go, tried using hasPassingGrade for “You passed/failed” but it doesn’t recognise it for some reason.

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 (getGrade(studentScore) === "A++" & getAverage(totalScores) === 50.8){
let message = "Class average: 50.8. Your grade: A++. You passed the course.";
return message;
} else if (getGrade(studentScore) === "F" & getAverage(totalScores) === 71.7){
let message ="Class average: 71.7. Your grade: F. You failed the course.";
return message;
}

}
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));

Your function should work for any set of scores, do not hardcode the values

Good point, I changed it to >60 and >=100 values, it is functional and logs fine, but I still get the same message.

///////////////////////////////////////////////////////////////////////////

  1. Your
studentMsg

function should return the correct message based on the student’s score and the class average.

///////////////////////////////////////////////////////////////////////////

I also changed the message for the + getGrade(studentScore) style, still the same :frowning:
Thank you for the help though!

Well, your function need to still work for all values

If we try random values like

console.log(studentMsg([32, 45, 12, 56, 11,  9, 45, 78, 91, 100], 72));

we get undefined

OH MY DAYS I just fixed it thanks to your input!! I moved over to this:

function studentMsg(totalScores, studentScore) {

if (studentScore > 60){

let message = "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + ". You passed the course.";

return message;

} else if (studentScore <= 60){

let message ="Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + ". You failed the course.";

return message;

}

}

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));

I realised I didn’t need to be that specific on my If / if else functions at all! The functions were still in use if I made the message an articulation of them instead of string. My goodness, thank you so much for that extra studentMsg! Made me realize how closed off my code was! :slight_smile:
