Document Fragment

• The DocumentFragment interface represents a minimal document object that has no parent.
• A common use for Document Fragment is to create one, assemble a DOM subtree within it, then append or insert the fragment into the DOM using Node interface methods such as appendChild( ) or insertBefore( ).
• Document fragment isn’t part of the active document tree structure, changes made to the fragment don’t affect the document.
• Doing this moves the fragment’s nodes into the DOM, leaving behind an empty Document Fragment.
• An empty Document Fragment can be created using the document.createDocumentFragment() method.

Create Document Fragment

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