My Solution in plain old JS5 :)

function fizzbuzz(value) {
    if (value % 5 == 0 && value % 3 == 0) {
        console.log("FizzBuzz")
    } else if (value % 5 == 0) {
        console.log("Buzz")
    } else if (value % 3 == 0) {
        console.log("Fizz")
    } else {
        console.log(value)
    }
};

function TestNumbers() {
for (var i = 0; i < 101; i++) {
    console.log(fizzbuzz(i));
    }
};

TestNumbers();
