### Ist Nebenläufigkeit besser als Parallelität?

Nein! Das ist nicht die Moral der Geschichte.

Nebenläufigkeit unterscheidet sich von Parallelität. Und sie ist besser bei **bestimmten** Szenarien, die viel Warten erfordern. Aus diesem Grund ist sie im Allgemeinen viel besser als Parallelität für die Entwicklung von Webanwendungen. Aber das stimmt nicht für alle Anwendungen.

Try to avoid using bitter sarcasm or potentially passive-aggressive comments. If something is wrong, it's better to be direct (try to be gentle) than sarcastic.

Try to be as specific and objective as possible, avoid generalizations.
