Ensuite, en arrière-plan, il mettra ces données JSON-compatible (par exemple un `dict`) à l'intérieur d'un `JSONResponse` qui sera utilisé pour envoyer la réponse au client.

Disons que vous avez une classe `Person`, avec une variable `name` :

Vous pouvez ensuite déclarer une variable de type `Person` :
