You cannot render a inside another . you should never have more than one in your app.

You cannot render a <router> inside another <router>. In most web frameworks, including React, Angular, and Vue, the router is responsible for managing the navigation and routing logic of the application. The router provides a way to map URL paths to specific components that should be rendered when those paths are accessed.

Typically, you would define a single top-level router component in your application. This router component is responsible for rendering different components based on the current URL. It should be placed at the root level of your application, wrapping all other components that need to be part of the routing system.

Here’s an example of how you can set up a router in a React application using the popular library React Router:

    {`
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

import Home from './components/Home';
import About from './components/About';
import NotFound from './components/NotFound';

const App = () => {
  return (
    
      
        
        
        
      
    
  );
};

export default App;
    `}
    
  

In this example, the <Router> component from React Router is used to wrap the routes defined inside the <Switch> component. The <Switch> component renders the first <Route> inside it that matches the current URL, falling back to the <Route> with no specified path if no other routes match. This allows for handling 404 errors or showing a default component when no other routes match.

It is important to note that you should only have one top-level router component in your application. This is because each router has its own internal state and routing logic, having multiple routers can cause conflicts and unexpected behavior.
