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

const Home = () => <h1>Home</h1>;
const About = (props) => <h1>About {props.name}</h1>;

const App = () => (
  <Router>
    <div>
      <nav>
        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/about">About</Link>
          </li>
        </ul>
      </nav>

      <Route path="/" exact component={Home} />
      <Route path="/about" render={() => <About name="John" />} />
    </div>
  </Router>
);

export default App;
