Hello!
Why is Redux listed under course prerequisites when in this course Redux is not needed by learner at all? Is this note reserved for potential upcoming additional lessons?

Hello,

I’m working on the react router. I don’t understand the component <Link>. I take this code from React-Router v5 and I don’t understand why it doesn’t work fine.
The problem, when I click on the link my component Home, or About, Dashboard is not loaded. Only the url is changed but not my component.

import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";


// You can think of these components as "pages"
// in your app.

function Home() {
  return (
    <div>
      <h2>Home</h2>
    </div>
  );
}

function About() {
  return (
    <div>
      <h2>About</h2>
    </div>
  );
}

function Dashboard() {
  return (
    <div>
      <h2>Dashboard</h2>
    </div>
  );
}


export default function App() {
  return (
    <Router>
      <div>
        <nav>
          <ul>
            <li>
              <Link to="/">Home</Link>
            </li>
            <li>
              <Link to="/about">About</Link>
            </li>
            <li>
              <Link to="/dashboard">Dashboard</Link>
            </li>
          </ul>
        </nav>

        <Switch>
          <Route exact path="/" component={Home} />
          <Route path="/about" component={About} />
          <Route path="/dashboard" component={Dashboard} />
        </Switch>
      </div>
    </Router>
  );
}

Ok I have found the problem. Be carefull of your versions.

Use React-router-dom V5 with React V16

OR use React-router-dom V6 with React V18
