Help us understand the problem. What is going on with this article?

setTimeout()を使ったループ処理

qiita.js
'use strict';

{
function showTime() {
console.log(newDate());
setTimeout(showTime, 1000);//繰り返す値と、1000ミリ秒(1秒)を引数に渡す
};

showTime();
}

結果として現在時刻を1秒毎に出力する。

上のコードだとループ処理になるため、指定した数字で止める処理は↓

qiita.js
'use strict';

{
 let i = 0;
 function showTime() {
    console.log(newDate());
    const timeoutId = setTimeout(showTime, 1000);
    i++;
    if(i > 3){  //3より大きい値になるまで処理
      clearTimeout(timeoutId)//clearTimeoutにsetTimeoutの返り値を定数に入れる
    }
  };

showTime();
}
