Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

I have tried to do this code but i got stuck and not getting the expected answer

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(hasPassedScore>60){
  return "Class average: "+getAverage(totalScores)+". Your grade: "+getGrade(studentScore)+"You passed the Course"+"."
}else if(hasPassedScore<60){
  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));

you have a syntax error, you have an unclosed string

fix that, and you get this:
ReferenceError: hasPassedScore is not defined

what are you trying to use?

function studentMsg(totalScores, studentScore) {

if(studentScore>60){

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

}else if(studentScore<60){

return "Class average: "+getAverage(totalScores)+". Your grade: "+getGrade(studentScore)+" You failed the Course"+"."

}

}

i got the expected answer however didn’t passes the test, don’t understand the problem

First failed test is

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." .

So, let’s add

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.");

at the bottom of the editor

It prints

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

can you see the differences? like missing punctuation, uppercase vs lowercase letters

yes now i got the same answer but still not passed

share your code please


function studentMsg(totalScores,studentScore) {
if(studentScore>60){
  return"Class average: "+getAverage(totalScores)+". Your grade: "+getGrade(studentScore)+" You passed the Course"+"." 
}else if(studentScore<60){
  return"Class average: "+getAverage(totalScores)+". Your grade: " +getGrade(studentScore)+"."+" You failed the course"+"."
}

}console.log(studentMsg([56,23,89,42,75,11,68,43,91,19],100));
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

the output came as below…
Class average: 51.7. Your grade: A++ You passed the Course.
Class average: 71.7. Your grade: F. You failed the course.

i dont know how to put quotation marks to whole answer as expected

i got my code done thank you so much

it was the case of letter as u mentioned …but thank you so much

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 (').

You are still failing the other test, so let’s add

console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));
console.log("Class average: 50.8. Your grade: A++. You passed the course.");

This gives

Class average: 50.8. Your grade: A++ You passed the Course.
Class average: 50.8. Your grade: A++. You passed the course.

You have similar issues, with punctuation and capitalization
