Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

my brain stop !
i need help i try all the methods

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) {
  
return ( "Class average:" + " " + getAverage(totalScores) + " Your grade:" + getGrade(studentScore) + " " + "You passed the course.");

}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

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."

.

This is the requested output, let’s look at yours as we have an handy console.log. I also add a second console.log with the expected string:

console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));
console.log("Class average: 71.7. Your grade: F. You failed the course.")

the output of this is:

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

let’s see the differences

-Class average: 71.7 Your grade:F You passed the course.
?                   |            | |     ||||
+Class average: 71.7. Your grade: F. You failed the course.

In words, you are missing two full stops and a space, and you give the wrong message.

For the punctuation you need to change the strings you are concatenating.
For the wrong message, you need to have a conditional statement in there to decide which message (passed/failed) to use.
