I think this is already great, but what do you think about putting one more hurdle before initialization? 🤩
Just in case that button is pressed against by people's intension.
things like..

  const handleReset = () => {
    if (window.confirm('초기화 하시겠습니까?') {
       setName('')
       ...
       alert('초기화 되었습니다.')
    }
  }
