Benchmark: replaceChild vs replaceChildren vs documentFragment more nodes

HTML Preparation code:

<div id="container"></div>

Script Preparation code:

var elements = [document.createElement('div'), document.createElement('div'),document.createElement('div'), document.createElement('div'),document.createElement('div'), document.createElement('div'), document.createElement('div'), document.createElement('div')];
var fragment = document.createDocumentFragment();
var container = document.getElementById('container');

elements.forEach(element => fragment.appendChild(element));
container.appendChild(fragment);

Tests:

replaceChild
var changeIndex = 1; elements[changeIndex] = document.createElement('div'); container.replaceChild(elements[changeIndex], container.children[changeIndex]);
replaceChildren
var changeIndex = 1; elements[changeIndex] = document.createElement('div'); container.replaceChildren(elements)
append documentFragment
var changeIndex = 1; var newChildren = document.createDocumentFragment(); elements[changeIndex] = document.createElement('div'); elements.forEach(element => newChildren.appendChild(element)); while(container.firstChild) { container.firstChild.remove(); } container.appendChild(newChildren)
