HTML Preparation code:

<div><div><div><div><div><div><div><div id='container'></div></div></div></div></div></div></div></div>

Tests:

Replacing the entire list with DocumentFragment
// Assume we have a parent div with id="container" let container = document.getElementById("container"); // Replacing the entire list with DocumentFragment for (let i = 0; i < 1000; i++) { let fragment = document.createDocumentFragment(); let newContainer = document.createElement("div"); let newElement = document.createElement("div"); newElement.textContent = "New Element " + i; newContainer.appendChild(newElement); fragment.appendChild(newContainer); container.replaceWith(fragment); container = newContainer; }
Clearing and using DocumentFragment to append new elements
// Assume we have a parent div with id="container" let container = document.getElementById("container"); // Clearing and using DocumentFragment to append new elements for (let i = 0; i < 1000; i++) { container.innerHTML = ''; let fragment = document.createDocumentFragment(); let newElement = document.createElement("div"); newElement.textContent = "New Element " + i; fragment.appendChild(newElement); container.appendChild(fragment); }
Replacing the entire list
// Assume we have a parent div with id="container" let container = document.getElementById("container"); // Replacing the entire list for (let i = 0; i < 1000; i++) { let newContainer = document.createElement("div"); let newElement = document.createElement("div"); newElement.textContent = "New Element " + i; newContainer.appendChild(newElement); container.replaceWith(newContainer); container = newContainer; }
Clearing and appending new elements
// Assume we have a parent div with id="container" let container = document.getElementById("container"); // Clearing and appending new elements for (let i = 0; i < 1000; i++) { container.innerHTML = ''; let newElement = document.createElement("div"); newElement.textContent = "New Element " + i; container.appendChild(newElement); }
