Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

It is able to return the failing message; however, once it was able to return that, it added another case to the problem. I noticed that the first case had a console log of the array; however the pass case did not. I entered in the pass case but it still does not work. The pass and fail case are basically the same code except one doesn’t work and I’m not sure what I am missing.

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";
}

  }
  else if(studentScore<=59){
    return studentMsg = "Class average: " + getAverage(totalScores) + ". Your grade: " + getGrade(studentScore) + ". You failed the course."
  }
  return " ";
}
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));

Welcome to the forum @mondoo.n

TypeError: studentMsg is not a function

You have an error in your function.

What is the studentMsg variable?

Happy coding

Actually helped me out a ton, thanks for that. Turns out I just had to initialize the variable as a string.
