title: JSON Parse error: Unexpected identifier "Not"
body: <p>I am working through the react-native tutorial at <a href="http://facebook.github.io/react-native/docs/tutorial.html#fetching-real-data" rel="nofollow">http://facebook.github.io/react-native/docs/tutorial.html#fetching-real-data</a> and after adding the function </p>
  
  <pre><code>fetchData: function() {
    fetch(REQUEST_URL)
      .then((response) =&gt; response.json())
      .then((responseData) =&gt; {
        this.setState({
          movies: responseData.movies,
        });
      })
      .done();
  },
  </code></pre>
  
  <p>to the AwesomeProject object and then reloading the iOS simulator, I get the error <code>JSON Parse error: Unexpected identifier "Not"</code>. Since I have not written any JSON, I do not know where this error could be coming from.</p>
