Definition and Usage

The createDocumentFragment() method creates a imaginary Node object, with all the properties and methods of the Node object.

The createDocumentFragment() method is usefull when you want to extract parts of your document, change, add, or delete, some of the content, and insert it back to your document.

You can also use the document's Document object to perform these changes, but to prevent destroying the document structure, it can be safer to extraxt only parts of the document, make the changes, and insert the part back to the document.

Note: Nodes being appended to the document fragment, from the document, will be removed from the document.
