How is .removeChild() useful for traversing the DOM if you still need to create a variable that holds a reference?

Does that make sense? In the last example, and in the code challenge, we had to create a reference to the child element before ever passing it into .removeChild(). If we have to select the child element before passing it into .removeChild(), can't we just remove the child node without also selecting the parent and then passing removeChild()?

I'm sure I'm missing something...thank you in advance!

You can remove an element without a reference to the parent using "remove", but it is a newer method and does not have as much browser support as "removeChild" does. Besides, it is easy to get an element's parent using the "parentNode" attribute.
