react react-router state-management javascript

I've searched everywhere and can't find a clear answer... I'm having trouble with nested routes in React Router 6 where the state of my parent component resets unexpectedly when navigating between routes. I have a parent component that holds some state, and I am using the `useLocation` hook to manage different child components based on the selected route. However, whenever I switch between these child routes, the parent state resets instead of persisting. Here's a simplified version of my setup: ```javascript import { BrowserRouter as Router, Routes, Route, Link, useLocation } from 'react-router-dom'; import { useState } from 'react'; const ParentComponent = () => { const [count, setCount] = useState(0); const location = useLocation(); return ( <div> <h1>Count: {count}</h1> <button onClick={() => setCount(count + 1)}>Increment</button> <nav> <Link to="/child1">Child 1</Link> <Link to="/child2">Child 2</Link> </nav> <Routes> <Route path="/child1" element={<ChildComponent1 />} /> <Route path="/child2" element={<ChildComponent2 />} /> </Routes> </div> ); }; const ChildComponent1 = () => <div>Child 1 Content</div>; const ChildComponent2 = () => <div>Child 2 Content</div>; const App = () => ( <Router> <ParentComponent /> </Router> ); export default App; ``` Every time I click on the links to navigate between `ChildComponent1` and `ChildComponent2`, the `count` state in `ParentComponent` resets back to `0`. I expected the state to persist since the `ParentComponent` doesn't unmount during these transitions. I've tried wrapping the state with `useReducer` to see if that helps, but the issue persists. I'm using React 18 and React Router 6. Is there something I'm missing regarding state persistence in nested routes? Should I be managing state differently to avoid this reset? The stack includes Javascript and several other technologies. Any ideas what could be causing this?
