Tell us what’s happening:

Hello,

Was wondering what was wrong with this code…

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";
  }
}


// User Editable Region

function hasPassingGrade(score) {
  if (score >=60 && <=100){
    return("true");
  }

  else if(score >=0 && <=59){
    return("false");
  }
}


console.log(hasPassingGrade(100));
console.log(hasPassingGrade(53));
console.log(hasPassingGrade(87));

when adding another condition you have to write out the whole condition.


 if(  x > 0 && x === 4){

this is an example. Notice how x is on both sides of &&

return(“true”); <— this returns (“true”) which is a string. You want to just return the boolean true; Same thing with returning false;

4

So this should be correct?:


function hasPassingGrade(score) {
  if (score >=60 && score <=100){
    return("true");
  }

  else if(score >=0 && score<=59){
    return("false");
  }
}


console.log(hasPassingGrade(100));
console.log(hasPassingGrade(53));
console.log(hasPassingGrade(87));

That better.
But you’re still returning a “string”.
return(“true”); ← this returns a string. You want it to return just true;

6

It works! But why does the tutorprompt say use the getGrade function when it is in fact a hasPassingGrade function

7

You’re right. I was just focussing on fixing your code. Sorry :sweat_smile:

In the hasPassingGrade function you have to make a call to getGrade with the score as the argument and what it returns can’t be “F”;

8

The instructions do in fact want you to use getGrade

9

How do you do that? And the exercise was already marked as completed…

Mean that trying to test and debugging it on it’s own editor in it’s own fcc curriculum.
