Benchmark: insertAdjacentHTML VS append VS appendChild (createDocumentFragment) [div only]

HTML Preparation code:

<div></div>

Tests:

append
let newElement = document.createElement("div"); let newElementPart = {}; for (i = 0; i < 1000; i++) { newElementPart = document.createElement("div"); newElement.append(newElementPart); } document.body.append(newElement);
insertAdjacentHTML
let html = "<div>"; for (i = 0; i < 1000; i++) { html += "<div></div>"; } html += "</div>"; document.body.insertAdjacentHTML("beforeend", html);
appendChild (createDocumentFragment)
let fragment_VDOM = document.createDocumentFragment(); let newElement = document.createElement("div"); let newElementPart = {}; for (i = 0; i < 1000; i++) { newElementPart = document.createElement("div"); newElement.appendChild(newElementPart); } fragment_VDOM.appendChild(newElement); document.body.appendChild(fragment_VDOM);
