Node Object
The replaceChild() method replaces a child node with a new node.
The new node could be an existing node in the document, or you can create a new node.
Tip: The replaced child node can be inserted later into any element in the same document. Use the insertBefore() or appendChild() method to insert it later into the same document, or use the adoptNode() or importNode() method to insert the replaced node into another document.
The replaceChild() method is supported in all major browsers.
