Welcome to [Kotlin](https://kotlinlang.org/)!   
It is an open-source, statically typed programming language supported and developed by [JetBrains](https://www.jetbrains.com/) and open-source contributors.

Some handy links:

 * [Kotlin Site](https://kotlinlang.org/)
 * [Getting Started Guide](https://kotlinlang.org/docs/tutorials/getting-started.html)
 * [Try Kotlin](https://play.kotlinlang.org/)

Então, vamos rever de um ponto de vista simplificado:

* O usuário digita o `username` e a `senha` no frontend e aperta `Enter`.
* O frontend (rodando no browser do usuário) manda o `username` e a `senha` para uma URL específica na sua API (declarada com `tokenUrl="token"`).
* A API checa aquele `username` e `senha`, e responde com um "token" (nós não implementamos nada disso ainda).

The [Alias] type now has an [Rhs] method that returns the type on the
right-hand side of its declaration: given `type A = B`, the `Rhs` of A

Tetapi kamu harus membaca terlebih dahulu **Tutorial - Pedoman Pengguna** (apa yang sedang kamu baca sekarang).

## Pydantic

All the data validation is performed under the hood by <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>, so you get all the benefits from it. And you know you are in good hands.

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters

## Çoklu Yol ve Sorgu Parametreleri

**FastAPI** neyin ne olduğunu ayırt edebileceğinden dolayı aynı anda birden fazla yol ve sorgu parametresi tanımlayabilirsiniz.

Ve parametreleri, herhangi bir sıraya koymanıza da gerek yoktur.

İsimlerine göre belirleneceklerdir:
