title: React JS not working with Internet Explorer 9
body: <p>I'm trying to use React with Internet Explorer 9 but getting the following errors even trying to run something very barebones:</p>
  
  <p><b>
  SCRIPT438: Object doesn't support property or method 'isArray'
  react-with-addons.js, line 4 character 317</p>
  
  <p>SCRIPT438: Object doesn't support property or method 'create'
  JSXTransformer.js, line 4 character 326
  </b></p>
  
  <p>I've read <a href="https://facebook.github.io/react/docs/working-with-the-browser.html" rel="nofollow noreferrer">https://facebook.github.io/react/docs/working-with-the-browser.html</a>, which says IE8 might have these issues, but no mention about IE9. Googling didn't really bring up any solutions either.</p>
  
  <p>Still, I tried adding es5-shim/sham as suggested on that page. That results in a different error:</p>
  
  <p><b>
  SCRIPT438: Object doesn't support property or method 'hasAttribute'
  es5-shim.min.js, line 6 character 4143
  </b></p>
  
  <p>Has anyone encountered these errors before in IE9 or otherwise?</p>
  
  <p>Thanks for the help!</p>
  
  <p>The full code I'm trying to run is:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html&gt;
  
  &lt;head&gt;
    &lt;script src="js/es5-shim.min.js"&gt;&lt;/script&gt;
    &lt;script src="js/es5-sham.min.js"&gt;&lt;/script&gt;
    &lt;script src="http://code.jquery.com/jquery-1.11.2.min.js"&gt;&lt;/script&gt;
    &lt;script src="js/react-with-addons.js"&gt;&lt;/script&gt;
    &lt;script src="js/JSXTransformer.js"&gt;&lt;/script&gt;
  
  &lt;/head&gt;
  
  &lt;body&gt;
    &lt;div id="container"&gt;&lt;/div&gt;
    &lt;script type="text/jsx"&gt;
      React.render(
      &lt;h1&gt;HELLO WORLD!&lt;/h1&gt;
      );
    &lt;/script&gt;
  &lt;/body&gt;
  
  &lt;/html&gt;</code></pre>
  </div>
  </div>
