createElement
const container = document.getElementById('container'); container.innerHTML = ''; for (let i = 0; i < 1000; i++) { const div = document.createElement('div'); const p = document.createElement('d'); p.classList.add('font-bold'); p.textContent = 'Hello'+i+'!'; div.appendChild(p); container.appendChild(div); } /*cleanup*/ container.innerHTML = '';
innerHTML
const container = document.getElementById('container'); container.innerHTML = ''; for (let i = 0; i < 1000; i++) { container.innerHTML += '<div><p class="font-bold">Hello'+i+'!</p></div>'; } /*cleanup*/ container.innerHTML = '';
innerHTML append
const container = document.getElementById('container'); container.innerHTML = ''; for (let i = 0; i < 1000; i++) { container.append('<div><p class="font-bold">Hello'+i+'!</p></div>'); } /*cleanup*/ container.innerHTML = '';
DocumentFragment
const container = document.getElementById('container'); container.innerHTML = ''; const fragment=document.createDocumentFragment(); for (let i = 0; i < 1000; i++) { const div = document.createElement('div'); const p = document.createElement('d'); p.classList.add('font-bold'); p.textContent = 'Hello'+i+'!'; div.appendChild(p); fragment.appendChild(div); } container.appendChild(fragment); /*cleanup*/ container.innerHTML = '';
