marketEventInstance(); FINE CODICE
effettua le seguenti modifiche: 1 Ottimizzazioni:
Rimozione delle chiamate ripetute a UserContext.book:
Nella funzione formatState, memorizza UserContext.book in una variabile locale book per evitare chiamate ripetute.
2 Standardizzazione:
Nomi delle funzioni di logging:
I nomi delle funzioni di logging siano standardizzati per essere coerenti e descrittivi.
3 Compattazioni:
Compatta le funzioni di logging in una singola funzione generica log che accetta parametri diversi.  Riscrivi tutto il codice mio, che ho postato sopra, con le modifiche indicate.
