node node type nodeName nodeValue
div element "div" null
em element "em" null
"abcd" text null "abcd"

Text nodes do not have a nodeName; the node value for an element node is underfined.

Element nodes have a getAttribute() and setAttribute) method. (only elements can have attributes)

Element nodes get the parent and childNodes properties from the Node object.

If you use a property on a node where that property doesn't apply, you'll get a value like "null" or "undefined"

Every node has a property called nodeType, along with nodeName and nodeValue. The nodeType property returns a number that maps to a value stored in the Node class.
