Node.parentNode

The Node.parentNode read-only property returns the parent of the specified node in the DOM tree.

parentNode = node.parentNode

parentNode is the parent of the current node. The parent of an element is an Element node, a Document node, or a DocumentFragment node.

if (node.parentNode) {
  // remove a node from the tree, unless
  // it's not in the tree already
  node.parentNode.removeChild(node);
}

Document and DocumentFragment nodes can never have a parent, so parentNode will always return null.

It also returns null if the node has just been created and is not yet attached to the tree.
