FastAPI will use this return type to:

* **Validate** the returned data.
    * If the data is invalid (e.g. you are missing a field), it means that *your* app code is broken, not returning what it should, and it will return a server error instead of returning incorrect data. This way you and your clients can be certain that they will receive the data and the data shape expected.

### Path fonksiyonu

"async def" yerine normal "def" ile bir *yol işlem işlevi* bildirdiğinizde, doğrudan çağrılmak yerine (sunucuyu bloke edeceğinden) daha sonra beklenen harici bir iş parçacığı havuzunda çalıştırılır.

Unfortunately, I can't simply trust PRs that just have several approvals.

Several times it has happened that there are PRs with 3, 5 or more approvals, probably because the description is appealing, but when I check the PRs, they are actually broken, have a bug, or don't solve the problem they claim to solve. 😅

So, it's really important that you actually read and run the code, and let me know in the comments that you did. 🤓

And still, you would probably not want the application to stay dead because there was an error in one place, you probably want it to **continue running** at least for the *path operations* that are not broken.
