Full Stack JavaScript Techdegree Student 354 Pointshow 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

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

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
