Benchmark: TreeWalker vs querySelectorAll to delete ids

HTML Preparation code:

<template id="template">

    <article id="442">
        <!-- article in start -->
        <h1>Lorem ipsum</h1>
        <p id="452">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Cumque, nostrum.</p>
        <!-- article in end -->

Script Preparation code:

window.cloneReference = () => {
  const fragment = document.createDocumentFragment();

  for(const el of reference.children) { fragment.append(el) }

  return fragment.cloneNode(true);
}

window.cloneTemplate = () => {
  return template.content.cloneNode(true);
}

window.container = document.querySelector("#container");

// need to create beforehand, as we are measuring performance of the method on a single node
window.treeWalker = document.createTreeWalker(
  container,
  NodeFilter.SHOW_ELEMENT,
  (node) => (node.id ? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_REJECT),
);

Tests:

TreeWalker (from reference)
container.innerHTML = ""; container.appendChild(cloneReference()); let element while (element = treeWalker.nextNode()) { element.removeAttribute("id"); } treeWalker.currentNode = container; // reset position
querySelector (from reference)
container.innerHTML = ""; container.appendChild(cloneReference()); let list = container.querySelectorAll('[id]'); let el; for (element of list) { element.removeAttribute("id"); }
TreeWalker (from template)
container.innerHTML = ""; container.appendChild(cloneTemplate()); let element while (element = treeWalker.nextNode()) { element.removeAttribute("id"); } treeWalker.currentNode = container; // reset position
querySelector (from template)
container.innerHTML = ""; container.appendChild(cloneTemplate()); let list = container.querySelectorAll('[id]'); let el; for (element of list) { element.removeAttribute("id"); }
