fizzbuz.js

function fizzbuz(target) {
    for (var i = 1; i <= target; i++) {
        linestr = i;
        if (i%3 == 0) {
            linestr = 'fizz';
            if (i%5 == 0){
                linestr = 'fizzbuzz';
            }
        } else if (i%5 == 0) {
            linestr = 'buzz';
        }
        console.log(linestr)
    }
    return 'done.'
}
