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

var changeIndex = 1; elements[changeIndex] = document.createElement('div'); var newChildren = document.createDocumentFragment(); elements.forEach(element => newChildren.appendChild(element)); container.replaceChild(elements[changeIndex], container.children[changeIndex]);
replaceChildren
var changeIndex = 1; elements[changeIndex] = document.createElement('div'); var newChildren = document.createDocumentFragment(); elements.forEach(element => newChildren.appendChild(element)); container.replaceChildren(elements)
