title: Reactjs : Append instead of replacing with render method
body: <p>I am new to ReactJs, and I am having lots of questions in my mind, for instance I want to append instead of replacing with render method,</p>
  
  <p>Can I <strong>safely and simply</strong> do this ?</p>
  
  <p>Creating a temporary div :</p>
  
  <pre><code>var temp = document.createElement('div');
  ReactDOM.render(&lt;NewElement /&gt;, temp);
  </code></pre>
  
  <p>and then appendChild : </p>
  
  <pre><code> document.getElementById("root").appendChild(temp)
  </code></pre>
  
  <p>Is it a clean way to do it ?</p>
