From Mozilla Developer Network:

The Node.cloneNode() method returns a duplicate of the node on which this method was called.

Cloning a node copies all of its attributes and their values, including intrinsic (in–line) listeners. It does not copy event listeners added using addEventListener() or those assigned to element properties. (e.g. node.onclick = fn) Moreover, for a element, the painted image is not copied.

The duplicate node returned by cloneNode() is not part of the document until it is added to another node that is part of the document using Node.appendChild() or a similar method. It also has no parent until it is appended to another node.

If deep is set to false, child nodes are not cloned. Any text that the node contains is not cloned either, as it is contained in one or more child Text nodes.

If deep evaluates to true, the whole subtree (including text that may be in child Text nodes) is copied too. For empty nodes (e.g. <img> and <input> elements) it doesn't matter whether deep is set to true or false.
