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.
