title: ReactJS issue when using capitalized methods
body: <p>Code pen link <a href="https://codepen.io/dbejju/pen/dwyvjQ" rel="nofollow noreferrer">here</a>.</p>
  
  <p>In my fist ReactJS tutorial video, I was writing hello world script and disappointingly its not working. I am not seeing any problem with the script or html tags I used but simple ReactDOM.Render() function isn't working. 
  Code pen SS below.

  <p>As you can see, the HTML block has root div
  HTML block:</p>
  
  <pre><code>&lt;div id="root"&gt;Why ReactDOM.Render() not working?&lt;/div&gt;
  </code></pre>
  
  <p>JS(Babel) block has simple render function and in the right side pane the preview is showing default text in root element but not the  text. </p>
  
  <p>JS block:</p>
  
  <pre><code>var el = &lt;h1&gt;YOU HELLO WORLD WHY DONT YOU WORK&lt;/h1&gt;
  ReactDOM.Render(
  el,
    Document.getElementById("root")
  )
  </code></pre>
