Dieses bestimmte reguläre Suchmuster prüft, ob der erhaltene Parameter-Wert:

* `^`: mit den nachfolgenden Zeichen startet, keine Zeichen davor hat.
* `fixedquery`: den exakten Text `fixedquery` hat.
* `$`: danach endet, keine weiteren Zeichen hat als `fixedquery`.

você está chegando de outro framework assíncrono que não faz o trabalho descrito acima e você está acostumado a definir triviais *funções de operação de rota* com simples `def` para ter um mínimo ganho de performance (cerca de 100 nanosegundos), por favor observe que no **FastAPI** o efeito pode ser bem o oposto. Nesses casos, é melhor usar `async def` a menos que suas *funções de operação de rota* utilizem código que performem bloqueamento <abbr title="Input/Output: disco lendo ou escrevendo, comunicações...

Aber sie erleichtert die Arbeit mit asynchronem Code erheblich.

Die gleiche Syntax (oder fast identisch) wurde kürzlich auch in moderne Versionen von JavaScript (im Browser und in NodeJS) aufgenommen.

Davor war der Umgang mit asynchronem Code jedoch deutlich komplexer und schwieriger.
