-   תכונות נוספות רבות (תודות ל - Starlette) כגון:
    -   **WebSockets**
    -   בדיקות קלות במיוחד מבוססות על `requests` ו - `pytest`
    -   **CORS**
    -   **Cookie Sessions**
    -   ...ועוד.

## ביצועים

- আরো অতিরিক্ত বৈশিষ্ট্য (স্টারলেটকে ধন্যবাদ) হিসাবে:
  - **WebSockets**
  - **GraphQL**
  - HTTPX এবং `pytest` ভিত্তিক অত্যন্ত সহজ পরীক্ষা
  - **CORS**
  - **Cookie Sessions**
  - ...এবং আরো।

## কর্মক্ষমতা

* Diğer ekstra özellikler (Starlette sayesinde):
    * **WebSocketler**
    * HTTPX ve `pytest` sayesinde aşırı kolay testler.
    * **CORS**
    * **Cookie Sessions**
    * ...ve daha fazlası.

## Performans

	lock    mutex // protects the following fields
	closing bool
	rrun    bool      // whether rt is running
	wrun    bool      // whether wt is running
	user    uint32    // user settable cookie
	rseq    uintptr   // protects from stale read timers
	rt      timer     // read deadline timer
	rd      int64     // read deadline (a nanotime in the future, -1 when expired)

!!! tip

    Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
