    Then APIStar stopped to exist as a server and Starlette was created, and was a new better foundation for such a system. That was the final inspiration to build **FastAPI**.

    I consider **FastAPI** a "spiritual successor" to APIStar, while improving and increasing the features, typing system, and other parts, based on the learnings from all these previous tools.

Das ist vergleichbar mit den HTTP-Statuscodes im Bereich 200 (von 200 bis 299). Diese „200“er Statuscodes bedeuten, dass der Request in einem bestimmten Aspekt ein „Success“ („Erfolg“) war.

Die Statuscodes im 400er-Bereich bedeuten hingegen, dass es einen Fehler gab.

Erinnern Sie sich an all diese **404 Not Found** Fehler (und Witze)?
