## Den `username` und das Format der Daten überprüfen

Wir verifizieren, dass wir einen `username` erhalten, und extrahieren die Scopes.

Sie könnten wie im Hamburger-Beispiel hin- und herspringen, zuerst das Wohnzimmer, dann die Küche, aber da Sie auf nichts warten 🕙, sondern nur putzen und putzen, hätte das Hin- und Herspringen keine Auswirkungen.

Es würde mit oder ohne Hin- und Herspringen (Nebenläufigkeit) die gleiche Zeit in Anspruch nehmen, um fertig zu werden, und Sie hätten die gleiche Menge an Arbeit erledigt.
