Node.removeChild()

The removeChild() method of the Node interface removes a child node from the DOM and returns the removed node.

Note: As long as a reference is kept on the removed child, it still exists in memory, but is no longer part of the DOM. It can still be reused later in the code. If the return value of removeChild() is not stored, and no other reference is kept, it will be automatically deleted from memory after a short time.

Unlike Node.cloneNode() the return value preserves the EventListener objects associated with it.

Inputs: child A Node that is the child node to be removed from the DOM.
