Recycling information stored in a Nodelist, which actually updates automatically, was not really useful for my purposes. Therefore, I converted my Nodelists into Arrays, which made it more static and a bit more convenient.
Converting these lists into a single Array is actually quite simple, here is how it goes:
let nList = document.querySelectorAll(".col"); let arr = Array.from(nList);
Having created a few <div class=”col”> before in my HTML file, I selected these with the first line and they automatically got stored into a Nodelist.
By storing my Nodelist via Array.from(nList) into the new variable called “arr”, I now have a fully functional Array available and can utilize it for all task necessary.
For further information, or for a polyfill to push back to up to IE6, you can look up the MDN documentation.
