JavaScriptでのFizzBuzz解答例

fizzbuzz01.js

var data = new Array();

for(var i=1; i<=100; i++){
  if(i%3 ===0||i%5 === 0){// 3か5で割り切れるとき
    var word = "";
    if(i%3 === 0){// 3で割り切れるとき
      word += "Fizz";// Fizz追加
    }
    if(i%5 === 0){// 5で割り切れるとき
      word += "Buzz";// Buzz追加
    }
    data.push(word);// FizzBuzzをpush
  }else{// その他の値はそのまま数値をpush
    data.push(i);
  }
}

for(var i=0; i<100; i++){
  console.log(data[i]+"\n");
}
