Ho sviluppato questo listato utilizzando JavaScript ES5 e desidero evitare l’uso delle funzionalità moderne di ES6. Vorrei un’analisi dettagliata di questo codice in italiano, focalizzandosi sui seguenti aspetti:
1.	Ridondanza di codice o controlli logici: Evidenziare eventuali duplicazioni o controlli logici non necessari.
2.	Ottimizzazioni: Indicare possibili miglioramenti per aumentare l’efficienza del codice.
3.	Compattazioni: Suggerire modi per rendere il codice più compatto.
4.	Miglioramento dell’efficienza e della velocità di esecuzione: Consigli su come ottimizzare le prestazioni del codice.
Per ciascuno dei punti da 1 a 4, sarebbero graditi suggerimenti specifici.   var CONFIG = {
