The root property for NodeIterator returns the Node that is the root on which the NodeIterator traverses. This is a read-only property.

Syntax:

root = nodeIterator.root;

Return Value: Returns the root Node.

Example: In this example, we will create a node iterator and will get the root node using this property.

HTML




<!DOCTYPE HTML>
<html>
  
<body style="text-align:center;">
    <h1 style="color:green;">
        neveropen
    </h1>
  
    <p>
        HTML | DOM NodeIterator root property
    </p>
  
  
    <button onclick="Geeks()">
        Click Here
    </button>
  
    <p id="a"></p>
  
    <script>
        var a = document.getElementById("a");
        function Geeks() {
            const nodeIterator = 
                document.createNodeIterator(
                document.body,
                NodeFilter.SHOW_ELEMENT,
                { acceptNode: function (node) 
                    { return NodeFilter.FILTER_ACCEPT; } },
                false
            );
            console.log(nodeIterator.root);
        }
