Es ist mehrmals passiert, dass es PRs mit drei, fünf oder mehr Zustimmungen gibt, wahrscheinlich weil die Beschreibung ansprechend ist, aber wenn ich die PRs überprüfe, sind sie tatsächlich fehlerhaft, haben einen Bug, oder lösen das Problem nicht, welches sie behaupten, zu lösen. 😅

Daher ist es wirklich wichtig, dass Sie den Code wirklich lesen und ausführen und mir in den Kommentaren mitteilen, dass Sie dies getan haben. 🤓
