Inserts `newNode` into `parent` at `index`, optionally replaceing the
current node at `index`. If `newNode` is a DocumentFragment, its childNodes
are inserted and removed from the fragment.
Inserts newNode into parent at index optionally replaceing the current node at index . If newNode is a DocumentFragment its childNodes are inserted and removed from the fragment .
