    let index = 0;
    let name = input[index++];
    let counterYes = 0;
    let counterNo = 0;
    let total = 301;

РЕШЕНИЕ СЪС SHIFT() И ТЕРНАРЕН ОПЕРАТОР:

    let name = input.shift();
    let counterYes = 0;
    let counterNo = 0;
    let total = 301;

    while (true) {

            break;
        }
        let dots = Number(input.shift()) * (zone === "Double" ? 2 : zone === "Triple" ? 3 : 1);

         _= total < dots ? counterNo++ : counterYes++;
        total -= total >= dots ? dots : 0;

        if (total === 0) {
            break;
        }
    }

    console.log( total === 0 ? `${name} won the leg with ${counterYes} shots.`
                             : `${name} retired after ${counterNo} unsuccessful shots.`);
