exit-hook provides a simple and reliable way to execute code when your Node.js process is about to exit. This is useful for cleanup tasks like closing database connections, writing logs, or releasing resources before the application terminates, whether due to an uncaught exception, signal interrupt (like Ctrl+C), or normal completion. It ensures crucial actions are performed even in abrupt shutdown scenarios, promoting data integrity and smooth application behavior.
