Answer 1

document.querySelector searches the entire page using a normal element iteration, while children[] is O(1).
Clearly, children is faster, especially with a large set of elements on the page.

Answer 2

Answer 3

It seems to me that you need to understand the events: https://owlcarousel2.github.io/OwlCarousel2/docs/a...
