Ich versuche, zwei Quadrate nebeneinander zu machen, eine, die eine zufällige Position wählt, und eine andere mit einer festen Position. Ich mache das, indem ich zwei Komponentenfunktionen mit jeweils unterschiedlichen Eigenschaften mache. Wenn ich jedoch versuche, die component2-Funktion hinzuzufügen, wird ein Fehler angezeigt, der das unerwartete Ende der Eingabe zum Ende meines Codes sagt. Dies verhindert, dass ich den Code ausführe. Was kann ich tun, um das zu beheben?Machen Sie zwei Quadrate mit zwei verschiedenen Funktionen, (JavaScript)

Sie jemals die 'component2' Funktion nicht schließen. add '' '' wo immer Sie es schließen wollen (ich werde vor 'startGame' gehen) – George
