Different types of nodes

document.nodeType === Node.DOCUMENT_NODE; // true
document.doctype.nodeType === Node.DOCUMENT_TYPE_NODE; // true

var fragment = document.createDocumentFragment();
fragment.nodeType === Node.DOCUMENT_FRAGMENT_NODE; // true

var p = document.createElement("p");
p.textContent = "Once upon a time...";

p.nodeType === Node.ELEMENT_NODE; // true
p.firstChild.nodeType === Node.TEXT_NODE; // true

Comments

This example checks if the first node inside the document element is a comment node, and if it is not, displays a message.

var node = document.documentElement.firstChild;
if (node.nodeType != Node.COMMENT_NODE)
  console.log("You should comment your code well!");
