    directly to JSON bytes via Pydantic when a return type or response model is
    set, which is faster and doesn't need a custom response class.

*Path operation decorator*'larınıza `responses` adlı bir parametre geçebilirsiniz.

Bu parametre bir `dict` alır: anahtarlar her response için status code'lardır (`200` gibi), değerler ise her birine ait bilgileri içeren başka `dict`'lerdir.

Crea un response como se describe en [Retorna un Response Directamente](response-directly.md) y pasa los headers como un parámetro adicional:

/// note | Detalles Técnicos

También podrías usar `from starlette.responses import Response` o `from starlette.responses import JSONResponse`.

/// note | Технічні деталі

Ви також можете використати `from starlette.responses import Response` або `from starlette.responses import JSONResponse`.

**FastAPI** надає ті самі `starlette.responses` як `fastapi.responses` лише для зручності для вас, розробника. Але більшість доступних відповідей надходять безпосередньо зі Starlette.

/// tip

You will normally have much better performance using a [Response Model](../tutorial/response-model.md) than returning a `JSONResponse` directly, as that way it serializes the data using Pydantic, in Rust.

///

## Return a `Response` { #return-a-response }

You can return a `Response` or any sub-class of it.

/// info

`JSONResponse` itself is a sub-class of `Response`.
