Benchmark: Fork of createElement vs insertAdjacentHTML but actually works V2 with spreading into an array

HTML Preparation code:

<div id="test"></div>

Tests:

createElement
const elemTpl = document.createElement("div"); elemTpl.classList.add("testClass"); newElement = document.createElement("div"); newElement.id = "testing"; const arr = new Array(); for (i = 0; i < 1000; i++) { arr.push(elemTpl.cloneNode(true)); } newElement.append(...arr); document.getElementById("test").appendChild(newElement);
insertAdjacentHTML
html = "<div id='testing'>" for (i = 0; i < 1000; i++) { html += "<div class='testClass'></div>"; } html += "</div>"; document.getElementById("test").insertAdjacentHTML("beforeend", html);
