Woow, that is brutal but good practise. Keep in mind that you can combine Monday-Friday and Saturday and Sunday and don't need to write out a case for each day individually. Otherwise you did not declare let price = 0 which is needed to avoid printing out a message when no valid price has been found.

function shopForFruits(arg1, arg2, arg3) {
    let fruit = arg1;
    let day = arg2;
    let quantity = Number(arg3);
    let price = 0;

    switch (day) {
        case "Monday":
            switch (fruit) {
                case "banana":
                    price = 2.5;
                    break;
                case "apple":
                    price = 1.2;
                    break;
                case "orange":
                    price = 0.85;
                    break;
                case "grapefruit":
                    price = 1.45;
                    break;
                case "kiwi":

Wait a minute, what is that console.log('fruit') doing in those switch-cases ???
