* **Sự hỗ trợ từ các trình soạn thảo**.
* **Kiểm tra kiểu dữ liệu (type checking)**.

...và **FastAPI** sử dụng các khia báo để:

* **Định nghĩa các yêu cầu**: từ tham số đường dẫn của request, tham số query, headers, bodies, các phụ thuộc (dependencies),...
* **Chuyển dổi dữ liệu*: từ request sang kiểu dữ liệu được yêu cầu.
* **Kiểm tra tính đúng đắn của dữ liệu**: tới từ mỗi request:

* **Data te converteren**: van de request naar het vereiste type.
* **Data te valideren**: afkomstig van elke request:

  /**
   * Returns a {@code char} matcher functionally equivalent to this one, but which may be faster to
   * query than the original; your mileage may vary. Precomputation takes time and requires more
   * memory, so it is only likely to be worthwhile if the precomputed matcher is queried very often.
   *

 *  New: `HttpUrl.addQueryParameter()` percent-escapes more characters.
    Previously several ASCII punctuation characters were not percent-escaped
    when used with this method. This does not impact already-encoded query
    parameters in APIs like `HttpUrl.parse()` and
    `HttpUrl.Builder.addEncodedQueryParameter()`.
 *  New: CBC-mode ECDSA cipher suites have been removed from OkHttp's default
