Problem with compile ReactJs: Error in App.js Unexpected token

Question

I followed the following command line.

npx create-react-app github-first-app

npm install --save react-tabs

npm i styled-components

npm install git-state --save

with the following code files

App.js

import React from "react";
import Layout from "./components/layout";
import NoSearch from "./components/no-search";
import Profile from "./components/profile";
import Repositories from "./components/repositories";
import useGithub from "./hooks/github-hooks";

const App = () => {
  const { githubState } = useGithub();
  return (
    <Layout>
      {githubState.hasUser ? (
        <>
          {githubState.loading ? (
            <p>Loading</p>
          ) : (
            <>
              <Profile />
              <Repositories />
            </>
          )}
        </>
      ) : (
        <NoSearch />
      )}
    </Layout>
  );
};

export default App;

and Index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

      manifest.json provides metadata used when your web app is installed on a
      user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
    -->
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <!--
      Notice the use of %PUBLIC_URL% in the tags above.
      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`.

  </body>

but

npm start

it fails completely with a message that doesn't help a novice at all.

Failed to compile.

./src/App.js Syntax error: C:/Workspace/bootcamps/022_CriandoUmFrontEndTotalmenteComponentizadoNaPraticaComReactJS/github- first-app/src/App.js: Unexpected token (13:9)

Could you tell me where I'm going wrong?

What happens if you replace <> with <React.Fragment>? (btw I don't think --save is needed anymore) — evolutionxbox

I'm not sure why but I find the <> fragment shorthand isn't always recognised. Try <React.Fragment> instead, and the same of course for the closing tag. (Line 13 is the <> tag, is how I'm suspecting this.) — Robin Zigmond

As per React documentation, support for JSX fragments is available in Babel v7.0.0-beta.31 and above!

Use <React.Fragment> instead
