Review JavaScript Fundamentals by Building a Gradebook App - Step 2

Tell us what’s happening:

Hey, I got stuck again. It keeps saysing “Your getGrade function should return “B” if the score is between 80 and 89.” Why is only that part of the function faulty?

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 (90<=score<=99) {
    return "A";
  } else if (80<=score<=89) {
    return "B";
  } else if (70<=score<=79) {
    return "C";
  } else if (60<=score<=69) {
    return "D";
  } else return "E";
}

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

to check if a value is in a range, this is not valid in JavaScript, you need to do two separate expressions
well, actually you need only one. The ceil is 100, and 100 is already captured by score === 100 so you don’t need to worry about values that are above 99

You can not do it like that. You need to use && AND operator.
