* Editör desteğiyle birlikte:
    * Otomatik tamamlama.
    * Tip kontrolü.
* Veri Doğrulama:
    * Veri geçerli değilse, otomatik olarak açıklayıcı hatalar gösterir.
    * Çok <abbr title="Derin / İç içe: Nested">derin</abbr> JSON nesnelerinde bile doğrulama yapar.
* Gelen verinin <abbr title="Dönüşüm: serialization, parsing, marshalling olarak da biliniyor">dönüşümünü</abbr> aşağıdaki veri tiplerini kullanarak gerçekleştirir:
    * JSON.

And then, that system (in this case **FastAPI**) will take care of doing whatever is needed to provide your code with those needed dependencies ("inject" the dependencies).

This is very useful when you need to:

* Have shared logic (the same code logic again and again).
* Share database connections.
* Enforce security, authentication, role requirements, etc.

* Editor support, including:
    * Completion.
    * Type checks.
* Validation of data:
    * Automatic and clear errors when the data is invalid.
    * Validation even for deeply nested JSON objects.
* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of input data: coming from the network to Python data and types. Reading from:
    * JSON.
    * Path parameters.
