### 其他形式的异步代码

这种使用 `async` 和 `await` 的风格在语言中相对较新。

但它使处理异步代码变得容易很多。

这种相同的语法（或几乎相同）最近也包含在现代版本的 JavaScript 中（在浏览器和 NodeJS 中）。

但在此之前，处理异步代码非常复杂和困难。

在以前版本的 Python，你可以使用多线程或者 <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>。但代码的理解、调试和思考都要复杂许多。

在以前版本的 NodeJS / 浏览器 JavaScript 中，你会使用"回调"，因此也可能导致“回调地狱”。

This isn't even Python, NestJS is a JavaScript (TypeScript) NodeJS framework inspired by Angular.

It achieves something somewhat similar to what can be done with Flask-apispec.

This style of using `async` and `await` is relatively new in the language.

But it makes working with asynchronous code a lot easier.

This same syntax (or almost identical) was also included recently in modern versions of JavaScript (in Browser and NodeJS).

But before that, handling asynchronous code was quite more complex and difficult.

    public void test_specialProtocols() {
        String sessionId = "test-session-022";
        urlFilter.init(sessionId);

        urlFilter.addInclude("(http|https|ftp|file)://.*");
        urlFilter.addExclude("javascript:.*");
        urlFilter.addExclude("mailto:.*");

        assertTrue(urlFilter.match("http://example.com/"));
        assertTrue(urlFilter.match("https://example.com/"));

Bu Python teknolojisi bile değil. NestJS, Angulardan ilham almış olan bir JavaScript (TypeScript) NodeJS framework'ü.

Flask-apispec ile yapılabileceklere nispeten benzeyen bir şey elde ediyor.

Ce n'est même pas du Python, NestJS est un framework JavaScript (TypeScript) NodeJS inspiré d'Angular.

Il réalise quelque chose de similaire à ce qui peut être fait avec Flask-apispec.
