Run results for: removeChild vs display="none" performance benchmark

This benchmark is a fork of a different one. This time, using a different way to iterate childs for display:none. I was worried the original benchmark was not being fair.

Test name	Executions per second
removeChild	105994488.0 Ops/sec
testing display none with different iterator	2310985472.0 Ops/sec

HTML Preparation code:

<div id="container"></div>

Script Preparation code:

var container = document.getElementById('container');
ul = document.createElement('ul');
var html = [];
    for ( var i=0; i<2000; i += 1 ) {
  	html.push(`<li>${i}</li>`);
}
 ul.innerHTML = html.join('');
 container.appendChild(ul);

Tests:

removeChild
var element = ul.firstElementChild; while (element) { ul.removeChild(element); element = ul.firstElementChild; }
testing display none with different iterator
var element = ul.firstElementChild; while (element) { element.style.display="none" element = element.nextElementSibling; }
