After using the useNavigate hook, how can I ensure that useEffect runs and triggers an initial render in my component?
Within the App.js component, which serves as the homepage with the "/" path, the following code is implemented:
const [contacts, setContacts] = useState([]);
useEffect(() => {
const retrieveContacts = async function () {
const response = await api.get("/");
setContacts(response.data);
};
retrieveContacts();
}, []);
In the Delete.js component, located at the "/delete" path, the following code is used:
async function deleteContact() {
await props.deleteContactHandler(contact._id);
navigate("/");
}
Initially, two contacts are retrieved from the database within the App.js component resulting in the displayed screen shown below:

Subsequently, when attempting to delete one of the contacts (Mike), and returning to the homepage upon confirmation, both contacts still appear on the screen.
This inconsistency occurs due to the failure of the useEffect function to execute after navigating back to the App.js component, thus not updating the list of contacts.
To address this issue, forcing an initial render of the App.js component after the useNavigate hook is triggered by invoking:
navigate("/").
is necessary. This action ensures that all components are refreshed, showing the most recent state without any remnants of previously deleted data.
