Error while running a new created React JS app in

Question

I have just created a new web app using WebStorm; it comes with a template and I haven't added any new code, but when I try to run it it shows this Error:

My index.js.

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();

My App.js

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';

class App extends Component {
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro">
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

export default App;

My App.test.js

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';

class App extends Component {
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro">
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

export default App;

Some one with WebStorm experience to help me out with this.

From the error message I can see that you are trying to run your React component with Node.js. Strange idea. React applications are run in browser, this is a client-side code, so you have to build your application, start the server it is hosted on (in applications created using File | New | Project... | React App, you should normally run npm run start to build the app and start dev server) and then run/debug it in browser using JavaScript Debug Run configuration.
