### `UJSONResponse` { #ujsonresponse }

Альтернативная реализация JSON-ответа с использованием <a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>.

/// info | Информация

Требуется установка `ujson`, например командой `pip install ujson`.

///

/// warning | Предупреждение

`ujson` менее аккуратен, чем встроенная реализация Python, в обработке некоторых крайних случаев.
