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

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) }
