My code won’t pass because hasPassingGrade() is not returning false.

I’ve console logged the hasPassingGrade function and it does in fact return false. Thank you for any help

  1. Your hasPassingGrade function should return false if the grade is an “F”.

Your code so far

const getAverage = (arr) => {
let totalMarks = 0
let averageMark = 0;
for(let item of arr){

   totalMarks =  totalMarks + item;

}
if(arr!==""){
  averageMark = totalMarks/arr.length;
  return averageMark;
}




}
const getGrade = (score) => { 

      const gradeRules = {
          "A+": [100, 100],
          "A": [90, 99],
          "B": [80, 89],
          "C":[70, 79],
          "D":[60, 69],
          "F":[0, 59]
      };

      for(let grade in gradeRules){
        const [min, max] = gradeRules[grade];
        if(score >= min && score <= max){
             return grade;
        };
          
      }

}

const hasPassingGrade = (gradeScore) => {
          return gradeScore !== "F";
}

const studentMsg = (arr, score) => {

 

       return `Class average: ${getAverage(arr)}. Your grade: ${getGrade(score)}. You ${hasPassingGrade(getGrade(score)) === true ? "passed":"failed"} the course.`

}

console.log(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100));

Hi @blacksharkchris

The hasPassingGrade function should use the getGrade function to get the letter grade, and use it to determine if the grade is passing. A passing grade is anything different from "F".

You need to use the getGrade function within the hasPassingGrade function.

Happy coding
