Benchmark: singular clone vs batch clone

Script Preparation code:

const DIV = document.createElement('div')
const SPN = document.createElement('span')
const BTN = document.createElement('button')
const INP = document.createElement('input')
const H2 = document.createElement('h2')
const H4 = document.createElement('h4')
const AX = document.createElement('a')
const UL = document.createElement('ul')
const LI = document.createElement('li')

Tests:

batch clone
let u0 = UL.cloneNode(true) let l0 = LI.cloneNode(true) let l1 = LI.cloneNode(true) let l2 = LI.cloneNode(true) u0.appendChild(l0) u0.appendChild(l1) u0.appendChild(l2) for (let i = 0; i < 200; ++i) { let ui = u0.cloneNode(true) let uj = ui.firstElementChild; let uk = uj.nextElementSibling; let ul = uk.nextElementSibling; }
singular clone
for (let i = 0; i < 200; ++i) { let u0 = UL.cloneNode(true) let l0 = LI.cloneNode(true) let l1 = LI.cloneNode(true) let l2 = LI.cloneNode(true) u0.appendChild(l0) u0.appendChild(l1) u0.appendChild(l2) }
querySelectorAll
let u0 = UL.cloneNode(true) let l0 = LI.cloneNode(true) let l1 = LI.cloneNode(true) let l2 = LI.cloneNode(true) u0.appendChild(l0) u0.appendChild(l1) u0.appendChild(l2) l0.dataset.f00='1'; l1.dataset.f00='2'; l2.dataset.f00='3'; for (let i = 0; i < 200; ++i) { let ui = u0.cloneNode(true) let uj = ui.querySelectorAll('[data-f00]'); }
