But then, the real world happens. A user clicks the \"Submit\" button five times in a row. The network lags. The user navigates away before the data loads. Suddenly, your console is red with errors, your loading spinners are stuck, and your application state is out of sync.\u003c\/p\u003e\u003cp\u003eYou try to fix it with boolean flags (isLoading, hasError).
