Element: attributes property

The Element.attributes property returns a live 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, attributes is a key/value pair of strings that represents any information regarding that attribute.

Value

A NamedNodeMap object.

         for (const attr of paragraph.attributes) {
