how would you store list item somewhere in the middle

Lets say we have 10 list items and we would like to choose the fifth one. I just got some basic knowledge from practicing, however if I do it same way I would have to using 1-4 list items to get the fifth one by using

4thlistItem.nextElementSibling

Is there any easier way how to do it?

Thanks

Here are the notes I copied on this section of the video:

Summary of elements to access the DOM:

https://javascript.info/searching-elements-dom

Accessing the first child: node.firstElementChild Access the second element in a list with: node.nextElementSibling or .list li:nth-child(2) Access the last element in a list with: node.lastElementChild Access the 2nd to last element by using the last element and: node.previousElementSibling You can access a previous sibling element (like a div, by using the .previousElementSibling as well.

Hopefully this helps, Hannah

If you are stepping through the child elements one at a time, your method may be the easiest. But if you are starting with a reference to the parent and wish to get directly to the fifth child, you might use:

parentElement.children[4]   // since the indexes begin with 0
