the index.js will render App.js because of code given clearly
    root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);
The App.js have a code written inside the function that is
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.js</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        >
          Learn React
        </a>
      </header>
