title: Check if react element is empty
body: <p>I don't want to render the title when description is empty</p>
  
  <pre><code>var description = &lt;MyElement /&gt;; // render will return nothing in render in some cases
  
  if (!description) { // this will not work because its an object (reactelement)
      return null;
  }
  
  &lt;div&gt;
       {title}
       {description}
  &lt;/div&gt;
  </code></pre>
  
  <p>Whats the correct way instead of !description to check if its empty?</p>
