Bạn đặt nó trên một hàm. Giống như một chiếc mũ xinh xắn (Tôi ddonas đó là lí do mà thuật ngữ này ra đời).

Một "decorator" lấy một hàm bên dưới và thực hiện một vài thứ với nó.

Trong trường hợp của chúng ta, decorator này nói **FastAPI** rằng hàm bên dưới ứng với **đường dẫn** `/` và một **toán tử** `get`.

Nó là một "**decorator đường dẫn toán tử**".

///

Bạn cũng có thể sử dụng với các toán tử khác:
