Pero siguiendo los pasos anteriores, FastAPI podrá hacer algunas optimizaciones de rendimiento.

## Detalles Técnicos

Las versiones modernas de Python tienen soporte para **"código asíncrono"** usando algo llamado **"coroutines"**, usando la sintaxis **`async` y `await`**.

Veamos esa frase por partes en las secciones siguientes:

* **Código Asíncrono**
* **`async` y `await`**

Sinon, le chemin `/users/{user_id}` correspondrait aussi à `/users/me`, la fonction "croyant" qu'elle a reçu un paramètre `user_id` avec pour valeur `"me"`.
