title: React.createClass is not a function
body: <p>I'm just using script tags to bring in the libraries.  The examples cited are using require.  Is there a way to avoid that?  The other libraries seem to load fine.</p>
  
  <p>I know this is depreciated but still wondering how to get the following example working:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;script crossorigin src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.26.0/babel.min.js"&gt;&lt;/script&gt;
      &lt;script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"&gt;&lt;/script&gt;
      &lt;script crossorigin src="https://cdn.jsdelivr.net/npm/create-react-class@15.6.2/create-react-class.js"&gt;&lt;/script&gt;
      &lt;script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"&gt;&lt;/script&gt;
      &lt;title&gt;React Example&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;div id='container'&gt;&lt;/div&gt;
      &lt;script type='text/jsx'&gt;
          var HelloComponent2 = React.createClass({
              render: function() {
                  return (
                      &lt;h1&gt;Hello, classical&lt;/h1&gt;
                  );
              }
          });
          ReactDOM.render(
              &lt;HelloComponent2 name='Blobby0' /&gt;,
              document.getElementById('container')
          );
      &lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
