reactでhabit trackerアプリを作ろう

  const weekDays = ["SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT"];
  const today = dayjs();
  const startDayOfWeek = today.startOf("week");

...
// 以下でループを行う
{weekDays.map((weekDay, index) => (
  <StatusDay key={index}>
    <p>{weekDay}</p>
    <p>{startDayOfWeek.add(index, "d").format("D")}</p>
  </StatusDay>
))}
