Benchmark: Appending list of elements

HTML Preparation code:

<div id="testDiv"></div>

Tests:

Node.appendChild(el) in loop
"use strict"; for (let i=0; i<100; i++) { const p = document.createElement("p"); p.textContent = i; testDiv.appendChild(p); } testDiv.innerHTML = "";
Element.append(...els)
"use strict"; const els = []; for (let i=0; i<100; i++) { const p = document.createElement("p"); p.textContent = i; els.push(p); } testDiv.append(...els); testDiv.innerHTML = "";
Node.appendChild(DocumentFragment) (DocumentFragment.appendChild(el) in loop)
"use strict"; const frag = document.createDocumentFragment(); for (let i=0; i<100; i++) { const p = document.createElement("p"); p.textContent = i; frag.appendChild(p); } testDiv.appendChild(frag); testDiv.innerHTML = "";
Node.appendChild(DocumentFragment) (DocumentFragment.append(...els))
"use strict"; const els = []; for (let i=0; i<100; i++) { const p = document.createElement("p"); p.textContent = i; els.push(p); } const frag = document.createDocumentFragment(); frag.append(...els); testDiv.appendChild(frag); testDiv.innerHTML = "";
innerHTML
"use strict"; let html = ""; for (let i=0; i<100; i++) { html += "<p>"+i+"</p>"; } testDiv.innerHTML = html; testDiv.innerHTML = "";
