Benchmark: insertAdjacentHTML VS append VS appendChild (createDocumentFragment) [MINIMAL]

HTML Preparation code:

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

Tests:

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