ParentNode.append()- Inserts a set of
Nodeobjects orDOMStringobjects after the last child of theParentNode.DOMStringobjects are inserted as equivalentTextnodes. ParentNode.prepend()- Inserts a set of
Nodeobjects orDOMStringobjects before the first child of theParentNode.DOMStringobjects are inserted as equivalentTextnodes.
