How to make a slider in pure JavaScript?

Question

JavaScript

I have an array .
I want to make the array move forward and each element of the array alternates the class with main_news.
It should be something like a slider.
How to do it?

Answer 1

NodeList is not an array. This is NodeList. And it can be "twisted" in both directions by moving Node nodes (append \ prepend, etc.). It remains only to fasten the animation (for starters).
You can also convert to an array, and twist using arrays.
