Tell us what’s happening:

Hey everyone,

Can you please help me figure out the error? Can’t seem to catch it, the result is correct on my end

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) {

const classAverage = getAverage(totalScores);
const letterGrade =  getGrade(studentScore);

  if (letterGrade == "F") {
  return "Class average:"+" "+ classAverage  +", "+  "Your grade:"+" " + letterGrade +". " + "You failed the course.";

  } else {
 return "Class average:"+" "+ classAverage  +", "+  "Your grade:"+" " + letterGrade +". " + "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));

the first failed test is

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 this to the editor to confront

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.");

this prints to the console

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

do you see the difference?
