// Change this number to see how well they scale repeat = 10;
Tests:
innerHTML
const box = document.createElement('div'); let html = ''; for (let i = 0; i < repeat; i++) html += '<div class="a b"><div>Test</div></div>'; box.innerHTML += html;
insertAdjacentHTML
const box = document.createElement('div'); let html = ''; for (let i = 0; i < repeat; i++) html += '<div class="a b"><div>Test</div></div>'; box.insertAdjacentHTML('beforeend', html);
appendChild
const box = document.createElement('div'); const els = []; for (let i = 0; i < repeat; i++) { const div2 = document.createElement('div'); div2.innerText = 'Test'; const div1 = document.createElement('div'); div1.className = 'a b'; div1.appendChild(div2); els.push(div1); } els.forEach(el => box.appendChild(el));
append
const box = document.createElement('div'); const els = []; for (let i = 0; i < repeat; i++) { const div2 = document.createElement('div'); div2.innerText = 'Test'; const div1 = document.createElement('div'); div1.className = 'a b'; div1.append(div2); els.push(div1); } box.append(...els);
insertAdjacentElement
const box = document.createElement('div'); const els = []; for (let i = 0; i < repeat; i++) { const div2 = document.createElement('div'); div2.innerText = 'Test'; const div1 = document.createElement('div'); div1.className = 'a b'; div1.insertAdjacentElement('beforeend', div2); els.push(div1); } els.forEach(el => box.insertAdjacentElement('beforeend', el));
