Tell us what’s happening:

Buenas tardes, busque ayuda en el foro pero no encontré una solución a mi duda. Porque la consola devuelve 3 “F” ? Gracias!

Your code so far

function getAverage(scores) {
  let sum = 0;

  for (const score of scores) {
    sum += score;
  }

  return sum / scores.length;
}

// User Editable Region

function getGrade(score) {
  if (score === 100){
    return "A++";
  } else if (score <= 90 && score >= 99){
    return "A";
  } else if (score <= 80 && score >= 89){
    return "B";
  } else if (score <= 70 && score >= 79){
    return "C";
  } else if (score <=60 && score >= 69){
    return "D";
  } else {
    return "F"
  }
}

console.log(getGrade(96));
console.log(getGrade(82));
console.log(getGrade(56));

// User Editable Region

can a number be both less than 90 and more than 99 at the same time?

Okey entiendo… deje mi código así, sigue sin pasar :

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"
  }
}

If I add this code

for (let i = 100; i > 0; i--) {
  console.log(i, getGrade(i))
}

The grades are like this:

100 A++
99 F
98 F
97 F
96 F
95 F
94 F
93 F
92 F
91 F
90 A
89 A
88 A
87 A
86 A
85 A
84 A

Discúlpame pero no entiendo, tengo que agregar ese bucle for a mi codigo?

The loop is to test your function with all possible values.

From the loop you can see that for a score of 99, your function returns F:
