Review JavaScript Fundamentals by Building a Gradebook App - Step 4

JavaScript

Tell us what’s happening:

if(getGrade(studentScore)===“F”)
{return ‘"’+“Class average: “+getAverage(totalScores)+”. Your grade: “+getGrade(studentScore)+”. You failed the course.”+‘"’}
else {return ‘"’+“Class average: “+getAverage(totalScores)+”. Your grade: “+getGrade(studentScore)+”. You passed the course.”+‘"’}

What’s wrong in this code, why its not taking me to next step, even though its giving the correct results

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)==="F")
  {return '"'+"Class average: "+getAverage(totalScores)+". Your grade: "+getGrade(studentScore)+". You failed the course."+'"'}
  else {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));
console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Hi there!
You have a function hasPassingGrade() for checking the condition. Also remove single quote marks around double quotes and addition operator.

3

You should not have extra quotes logged around the messages, so remove all of those.

Also, you should think about using hasPassingGrade instead of getGrade

4

yes I got it, by adding the function hasPassingGrade()
also i removed the quotation.
