Create a Custom React Hook to Persist URL Query Params with `react-router-dom`
- To address the challenge of losing query parameters during route changes in a React app, a custom React hook called useNavigateWithQuery using react-router-dom is created.
- The useNavigateWithQuery hook preserves the existing query parameters from the current route by wrapping React Router's useNavigate and useLocation hooks.
- By using the useNavigateWithQuery hook instead of useNavigate directly, query parameters are automatically carried over to the next route, maintaining the user's context.
- This hook is beneficial for scenarios like dashboards, admin panels, or applications with filters and pagination where maintaining query parameters is crucial for a seamless user experience.
