Problem with the Step 4 of - Review JavaScript Fundamentals by Building a Gradebook App, Completed

JavaScript

  1. Go to the problem.
  2. Reset the page to make sure the page is set up by default.
  3. Press run the code.
  4. You will find the following console log statements.
// running tests 

1. Your function call of studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37) should return the following message: "Class average: 71.7. Your grade: F. You failed the course."


.2. 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." 

3. Your studentMsg function should return the correct message based on the student's score and the class average. // tests completed // console output undefined

To start, the step 4 just give you one studentMsg console.log.
That is: console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

The second studenMsg console.log isn’t provided by the exercise but its requested after you try to run the code.
Its missing: console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

After doing the code right what i consider being correct, as what were requested, it continue saying that something its not right. The only thing that i could not did is include " to show in my final console.log statement, im not sure that this might be the error.

Is the exercise with a bug?

Following, my whole code:
Observation: I have added manually the second missing and requested console.log statement in my code example, which is:

console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

My final console.log answer is:

Class average: 71.7.Your grade: F.You failed the course.
Class average: 50.8.Your grade: A++.You passed the course.

Not a big deal exercise, but any help is well appreciated as if its indeed a bug, hope i have contributed for something.

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) !== "F") {
    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));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

The problem is with the spaces left in the return string after the full stops. Try fixing that and your code should run just fine.

You are absolutely right. Thanks a lot! I also just had perceived that now lol. Such a small detail. Thanks for your help!

But i think the exercise still with the “bug” that the second requested studentMsg console.log isn’t included by default.

Should i delete this post of mine?

it’s not a bug, if you want to see more outputs of the function you can add them

You don’t have to. It will be of help to a person with a similar challenge
