JSON Schemaの最新バージョンでは<a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>というフィールドを定義していますが、OpenAPIは`examples`を持たない古いバージョンのJSON Schemaをベースにしています。

## Технічні деталі

Клас `BackgroundTasks` походить безпосередньо з <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.

Він імпортується безпосередньо у FastAPI, щоб Ви могли використовувати його з `fastapi` і випадково не імпортували `BackgroundTask` (без s в кінці) з `starlette.background`.
