* `100`以上は「情報」のためのものです。。直接使うことはほとんどありません。これらのステータスコードを持つレスポンスはボディを持つことができません。
* **`200`** 以上は「成功」のレスポンスのためのものです。これらは最も利用するであろうものです。
    * `200`はデフォルトのステータスコードで、すべてが「OK」であったことを意味します。
    * 別の例としては、`201`（Created）があります。これはデータベースに新しいレコードを作成した後によく使用されます。
    * 特殊なケースとして、`204`（No Content）があります。このレスポンスはクライアントに返すコンテンツがない場合に使用されます。そしてこのレスポンスはボディを持つことはできません。
