Get the node types of the <body> element's child nodes:

var c = document.body.childNodes;
var txt = "";
var i;
for (i = 0; i < c.length; i++) {
    txt = txt + c[i].nodeType + "<br>";
}

document.getElementById("demo").innerHTML = txt;

The result of txt will be:

3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
8    // comment node
3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
1    // element node

var x = document.getElementById("myDIV").firstChild;
var txt = "";
txt += "The node name: " + x.nodeName + "<br>";
txt += "The node value: " + x.nodeValue + "<br>";
txt += "The node type: " + x.nodeType;
</script>

The result of txt will be:

The node name: #text
