Remove an element ( and its children ) from the DOM

Via the MDN reference I want to simply do:

parent_element.removeChild(child_element);

However, in this particular case child_element has its own child elements.

Can I assume that this will not cause any problems and that they too will be removed.

The examples given in the reference did not make complete sense.

If the children didnt get removed, where or how could they exist in the DOM, unless someone put them somewhere else.

Yes when you remove an element from the DOM, all of its children are removed with it. If you are working with a modern browser, this is pretty safe. Older browsers tended to get memory leaks if you did not first remove all your event handlers before removing the elements.

Yes, all elements that are childs of a removed element are removed. You don't need to implement a deep removal yourself.
