extractContents
The extractContents() method of the Range interface is similar to a combination of Range.cloneContents() and Range.deleteContents(). It removes the child Nodes of the range from the document, clones them, and returns them as a new DocumentFragment object. For partially selected nodes, only the selected text is deleted, but all containing parent nodes up to the common ancestor are cloned as well, resulting in two copies of these nodes, one in the original document and one in the extracted fragment.
