HTML Preparation code:
<div id="container"></div>
Script Preparation code:
const node = document.getElementById('container'); for(let i = 0; i < 10000; i++) { node.appendChild(document.createElement('div')); }
Tests:
replaceChildren
const node = document.getElementById('container'); const elems = []; for(let i = 0; i < 10000; i++) { elems.push(document.createElement('div')); } node.replaceChildren(...elems);
while w/ appendChild
const node = document.getElementById('container'); const elems = []; for(let i = 0; i < 10000; i++) { elems.push(document.createElement('div')); } while (node.firstChild) { node.removeChild(node.lastChild); } for(let i = 0; i < 10000; i++) { node.appendChild(elems[i]); }
replaceChildren w/ fragments
const fragment = document.createDocumentFragment(); const node = document.getElementById('container'); const elems = []; for(let i = 0; i < 10000; i++) { elems.push(document.createElement('div')); } for(let i = 0; i < 10000; i++) { fragment.appendChild(elems[i]); } node.replaceChildren(fragment);
innerHTML w/ fragments
const fragment = document.createDocumentFragment(); const node = document.getElementById('container'); const elems = []; for(let i = 0; i < 10000; i++) { elems.push(document.createElement('div')); } for(let i = 0; i < 10000; i++) { fragment.appendChild(elems[i]); } node.innerHTML = ''; node.appendChild(fragment);
while w/ fragments
const fragment = document.createDocumentFragment(); const node = document.getElementById('container'); const elems = []; for(let i = 0; i < 10000; i++) { elems.push(document.createElement('div')); } for(let i = 0; i < 10000; i++) { fragment.appendChild(elems[i]); } while (node.firstChild) { node.removeChild(node.lastChild); } node.appendChild(fragment);
