It will be replaced with the URL of the `public` folder during the build.      Only files inside the `public` folder can be referenced from the HTML.      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will      work correctly both with client-side routing and a non-root public URL.      Learn how to configure a non-root public URL by running `npm run build`.    -->    <title>React App</title>  </head>  <body id="root"></body></html>
