### Переваги використання `Annotated` { #advantages-of-annotated }

Використання `Annotated` є рекомендованим замість задання значення за замовчуванням у параметрах функції, оскільки воно краще з кількох причин. 🤓

```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

  /**
   * Implementation of {@link Stream#flatMap} with an object spliterator output type.
   *
   * <p>To avoid having this type, we could use {@code FlatMapSpliterator} directly. The main
   * advantages to having the type are the ability to use its constructor reference below and the
   * parallelism with the primitive version. In short, it makes its caller ({@code flatMap})
   * simpler.

O **FastAPI** é todo baseado nesses type hints, eles oferecem muitas vantagens e benefícios.

Mas mesmo que você nunca use o **FastAPI**, você se beneficiaria de aprender um pouco sobre eles.

### `Annotated`’ın avantajları { #advantages-of-annotated }

Fonksiyon parametrelerindeki varsayılan değer stiline göre **`Annotated` kullanmanız önerilir**; birden fazla nedenle **daha iyidir**. 🤓

  public static long copy(Readable from, Appendable to) throws IOException {
    // The most common case is that from is a Reader (like InputStreamReader or StringReader) so
    // take advantage of that.
    if (from instanceof Reader) {
      // optimize for common output types which are optimized to deal with char[]
      if (to instanceof StringBuilder) {

```Python
q: Annotated[str, Query()] = "rick"

...или в старой кодовой базе вы увидите:

```Python

```

### Преимущества `Annotated` { #advantages-of-annotated }

**Рекомендуется использовать `Annotated`** вместо задания значения по умолчанию в параметрах функции — так **лучше** по нескольким причинам. 🤓

因此，你可以（且更推薦）這樣寫：

```Python
q: Annotated[str, Query()] = "rick"
```

…或在較舊的程式碼中你會看到：

```Python
q: str = Query(default="rick")
```

### `Annotated` 的優點 { #advantages-of-annotated }

建議使用 `Annotated`，而不是在函式參數上使用（舊式的）預設值寫法，理由很多，且更好。🤓

函式參數的「預設值」就是「實際的預設值」，這在 Python 的直覺上更一致。😌

你也可以在沒有 FastAPI 的其他地方「直接呼叫」同一個函式，而且能「如預期」運作。若有「必填」參數（沒有預設值），你的「編輯器」會提示錯誤，「Python」在執行時也會抱怨你未傳遞必填參數。
