Benchmark: for vs foreach DOM elements

HTML Preparation code:

<span id="democlass">
	<h1 class="ob-recIdx-0">Hello World</h1>
    <h1 class="ob-recIdx-1">Hello World</h1>
    <h1 class="ob-recIdx-2">Hello World</h1>
    <h1 class="ob-recIdx-3">Hello World</h1>
    <h1 class="ob-recIdx-4">Hello World</h1>
</span>

Tests:

for
var count = document.querySelectorAll('#democlass h1').length; for (var i = 0; i < count; i++) { //let currentIndex = String(i); var currentElement = document.querySelector('.ob-recIdx-' + i); currentElement.style.visibility = "hidden"; currentElement.classList.add('playerPlay'); }
forEach
var arr = document.querySelectorAll('#democlass h1'); arr.forEach(function(element){ element.style.visibility = "hidden"; element.classList.add('playerPlay'); });
