## Adicionando expressões regulares

Você pode definir uma <abbr title="Uma expressão regular, regex ou regexp é uma sequência de caracteres que define um parâmetro de busca para textos.">expressão regular</abbr> que combine com um padrão esperado pelo parâmetro:

Agora o cliente irá receber a mesma resposta *HTTP 500 Internal Server Error*, mas o servidor terá nosso `InternalError` personalizado nos logs. 😎

## Execução de dependências com `yield`

A sequência de execução é mais ou menos como esse diagrama. O tempo passa do topo para baixo. E cada coluna é uma das partes interagindo ou executando código.

之所以稱為「非同步」，是因為電腦/程式不需要與那些耗時的任務「同步」，等待任務完成的精確時間，然後才能取得結果並繼續工作。

相反地，非同步系統在任務完成後，可以讓任務稍微等一下（幾微秒），等待電腦/程式完成手頭上的其他工作，然後再回來取得結果繼續進行。

相對於「非同步」（asynchronous），「同步」（synchronous）也常被稱作「順序性」（sequential），因為電腦/程式會依序執行所有步驟，即便這些步驟涉及等待，才會切換到其他任務。

### 並行與漢堡

上述非同步程式碼的概念有時也被稱為「並行」，它不同於「平行」。

並行和平行都與 "不同的事情或多或少同時發生" 有關。

但並行和平行之間的細節是完全不同的。

為了理解差異，請想像以下有關漢堡的故事：
