<h2>Übung 4: Benutzerzugang verwalten</h2>
|
|
<p>
|
|
In dieser Übung ist es deine Aufgabe, den folgenden Code zu vereinfachen und dabei alle Techniken und
|
|
Prinzipien anzuwenden, die du bisher gelernt hast. Der vorgegebene Code simuliert ein
|
|
Benutzerverwaltungssystem mit verschiedenen Berechtigungen und Zuständen. Dein Ziel ist es, die Funktion
|
|
<code>manageUserAccess</code> zu überarbeiten, um die Logik sauberer und lesbarer zu machen, indem du die
|
|
Komplexität der verschachtelten Bedingungen reduzierst.
