The Element.append() method inserts a set of Node objects or strings after the last child of the Element. Strings are inserted as equivalent Text nodes.
Differences from Node.appendChild():
- Element.append() allows you to also append strings, whereas Node.appendChild() only accepts Node objects.
- Element.append() has no return value, whereas Node.appendChild() returns the appended Node object.
- Element.append() can append several nodes and strings, whereas Node.appendChild() can only append one node.
