Arrow functions do not have an arguments binding. However, they have access to the arguments object of the closest non-arrow parent function. Named and rest parameters are heavily relied upon to capture the arguments passed to arrow functions. In most cases, using rest parameters is a good alternative to using arguments.

var sum = (...arguments) => {
    total = 0;
    for (i in arguments) {
        total += arguments[i]
    }
    console.log(total);
}
sum(20, 80, 90, 70); // returns 260
