HTML Preparation code:

<div id="parent"></div>

Script Preparation code:

const node = document.getElementById('parent');
const child = document.createElement('div')
child.classList.add('child')
child.textContent = 'some text'

for(var i = 0; i < 5000; i++) node.appendChild(child);

Tests:

innerHTML
const node = document.getElementById('parent'); node.innerHTML = '';
replaceChildren
const node = document.getElementById('parent'); node.replaceChildren();
remove by while
const node = document.getElementById('parent'); while(node.firstChild) node.firstChild.remove()
removeChild by while
const node = document.getElementById('parent'); while(node.firstChild) node.removeChild(node.firstChild)
remove by forEach
const node = document.querySelectorAll('.child'); for (const child of node) child.remove()
