Adds a node to the end of the list of children of a specified parent node.

.attributes is a collection of all attribute nodes registered to the specified node.
.attributes is a collection of all attribute nodes registered to the specified node. It is a NamedNodeMap,not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attribute is a key value pair of strings that represents any information regarding that node; it cannot hold Object. Attribute can hold additional data/information that is required while processing custom JavaScript. There are many predefined attributes for different nodes used for binding events, validations, and specifying layout informations that are handled by browser (may vary from browser to browser).

Returns a DOMString representing the local part of the qualified name of an element.
Returns a DOMString representing the local part of the qualified name of an element. In Firefox 3.5 and earlier, the property upper-cases the local name for HTML elements (but not XHTML elements). In later versions, this does not happen, so the property is in lower case for both HTML and XHTML. Though the specification requires localName to be defined on the Node interface, Gecko-based browsers implement it on the Element interface.
MDN

The Element interface represents part of the document. This interface describes methods and properties common to each kind of elements. Specific behaviors are described in the specific interfaces, inheriting from Element: the HTMLElement interface for HTML elements, or the SVGElement interface for SVG elements.
