create-react-app generates function instead of class in App.js : <p>I'm trying to create react app using create-react-app command,
and it's generating the App.js file as function (es5 syntax without class)
instead of class (Example in the following code):</p>

<pre><code>import React from 'react';
import logo from './logo.svg';
import './App.css';

function App() {
  return (
    &lt;div className="App"&gt;
      &lt;header className="App-header"&gt;
        &lt;img src={logo} className="App-logo" alt="logo" /&gt;
        &lt;p&gt;
          Edit &lt;code&gt;src/App.js&lt;/code&gt; and save to reload.
        &lt;/p&gt;
        &lt;a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        &gt;
          Learn React
        &lt;/a&gt;
      &lt;/header&gt;
    &lt;/div&gt;
  );
}

export default App;
</code></pre>

<p>How can I force create-react-app to generate class instead?</p>
