### `ORJSONResponse`

上で読んだように、<a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>を使った、高速な代替のJSONレスポンスです。

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>を使った、代替のJSONレスポンスです。

/// warning | 注意

`ujson` は、いくつかのエッジケースの取り扱いについて、Pythonにビルトインされた実装よりも作りこまれていません。
