More Examples
This example demonstrates how whitespace may interfare:
Try to get the node name of the last child node of "myDIV":
<div id="myDIV">
<p>Looks like first child</p>
<p>Looks like last Child</p>
</div>
<script>
let text = document.getElementById("myDIV").lastChild.nodeName;
</script>

However, if you remove the whitespace from the source, there are no #text nodes in "myDIV":
<div id="myDIV"><p>First child</p><p>Last Child</p></div>
<script>
let text = document.getElementById("myDIV").lastChild.nodeName;
</script>
