/**
 * A map-like data structure that wraps a backing map and caches values while iterating through

在這裡，你將會看到**不同主題**的範例或「如何使用」的指南。

大多數這些想法都是**獨立**的，在大多數情況下，你只需要研究那些直接適用於**你的專案**的東西。

如果有些東西看起來很有趣且對你的專案很有用的話再去讀它，否則你可能可以跳過它們。

Для работы в режиме продакшн вместо `fastapi dev` нужно использовать `fastapi run`. 🚀

Внутри **FastAPI CLI** используется <a href="https://www.uvicorn.dev" class="external-link" target="_blank">Uvicorn</a>, высокопроизводительный, готовый к работе в продакшне ASGI-сервер. 😎

## `fastapi dev` { #fastapi-dev }

Вызов `fastapi dev` запускает режим разработки.
