Benchmark: for vs for..of vs NodeList.forEach vs Array.forEach vs jQuery.each

HTML Preparation code:

<content id="demo">Hello World!</content>
<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>

Script Preparation code:

let content = '';
for (let i=0; i<10000; i+=1) {
    content += '<div class="component" data-component="component' + i + '">Content ' + i + '</div>';
}
document.getElementById("demo").innerHTML = content;

Tests:

for
let components = []; let values = []; const queryComponentsFor = document.querySelectorAll('[data-component]'); for (let i = 0; i < queryComponentsFor.length; ++i) { values.push(queryComponentsFor[i].getAttribute('data-component')); components.push(queryComponentsFor[i]); }
for..of
let components = []; let values = []; for (let el of document.querySelectorAll('[data-component]')) { values.push(el.getAttribute('data-component')); components.push(el); }
NodeList.forEach
let components = []; let values = []; document.querySelectorAll('[data-component]').forEach(el => { values.push(el.getAttribute('data-component')); components.push(el); });
Array.forEach
let components = []; let values = []; [...document.querySelectorAll('[data-component]')].forEach(el => { values.push(el.getAttribute('data-component')); components.push(el); });
jQuery.each
let components = []; let values = []; $('[data-component]').each((i, el) => { values.push(el.getAttribute('data-component')); components.push(el); });
