Benchmark: NodeList vs Array iterator 3

HTML Preparation code:

<ul>
</ul>

Script Preparation code:

var ul = document.querySelector('ul');
for(var i=0;i<100;i++) {
  ul.appendChild(document.createElement('li'));
}

var nodeList = document.querySelectorAll('li');
var array = Array.from(nodeList);

Tests:

nodeList
for (const i of nodeList) { i.classList.add("hi"); }
array
for (const i of array) { i.classList.add("hi"); }
created array
let a2 = Array.from(nodeList); for (const i of a2) { i.classList.add("hi"); }
spread array
let a3 = [...nodeList]; for (const i of a3) { i.classList.add("hi"); }
