How to use Js CloneNode()

The CloneNode() method is used to create a copy of a node.

Syntax:

Parameters:
deep: Optional parameter that specifies whether to deep clone the node. If set to true, the node and its entire subtree will be cloned. If set to false, only the current node will be cloned, not the children. Default value is false.

var originalNode = document.getElementById("originalNode");
var clonedNode = originalNode.cloneNode(true);

In the example above, we first use the getElementById() method to retrieve an original node called originalNode. Then we clone this node using the cloneNode() method, creating a copy that includes all the child nodes and attributes of the original node. Finally, we assign the cloned node to a variable called clonedNode.
