title: Can't find what the unexpected token on React Native project
body: <p>Start my app with very simple code but have <code>SyntaxError /Users/user/myApp/index.ios.js: Unexpected token (7:6)</code>. </p>
  
  <pre><code>import React, { Component } from 'react';
  import { AppRegistry, Text } from 'react-native';
  
  class HelloWorldApp extends Component {
    render() {
      return (
        &lt;Text&gt;Hello world!&lt;/Text&gt;
      );
    }
  }
  
  AppRegistry.registerComponent('HelloWorldApp', () =&gt; HelloWorldApp);
  </code></pre>
  
  <p>Can't understand where is my mistake. I tried <code>rm -rf node_modules</code> and <code>npm install</code>, tried <code>npm chache clen</code> and <code>watchman watch-del-all</code> but still get error.</p>
