    function getGrade(score) {
    let grade;
    // Write your code here
    const ranges = [
        { max: 5, grade: 'F' },
        { max: 10, grade: 'E' },
        { max: 15, grade: 'D' },
        { max: 20, grade: 'C' },
        { max: 25, grade: 'B' },
        { max: 30, grade: 'A' }
    ];
    for(const {max, grade} of ranges){
        if (score <= max) return grade;

    Another solution close to if else but much more clean code: function getGrade(score) { let grade; // Write your code here const ranges = [ { max: 5, grade: 'F' }, { max: 10, grade: 'E' }, { max: 15, grade: 'D' }, { max: 20, grade: 'C' }, { max: 25, grade: 'B' }, { max: 30, grade: 'A' } ]; for(const {max, grade} of ranges){ if (score <= max) return grade; }

    return grade;

    }

    Using Ternary Operator

    function getGrade(score) { // Write your code here

    return (score>25 && score<=30)?'A':(score>20 && score<=25)?'B':(score>15 && score<=20)?'C':(score>10 && score<=15)?'D':(score>5 && score<=10)?'E':'F';

    }
