<li>Coffee</li>

<p>Click the button to see if the ul element has any child nodes.</p>
<button onclick="myFunction()">Try it</button>
<p>Try removing the child nodes of the list element, and the result will be false instead of true.</p>
<p><strong>Note:</strong> Whitespace inside a node is considered as text nodes, so if you leave any white space or line feeds inside an element, that element still has child nodes.</p>
