Benchmark: native fastest selector

HTML Preparation code:

<div id="root"></div>

Script Preparation code:

let root = document.querySelector('#root');
for(let n=1; n<=1000; n++)
	root.insertAdjacentHTML("beforeend", '\n<div class="outer"><div><div><div><div><div><div><div><div><div><div><div><div><div><div><div><div class="inner">Test</div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>');

Tests:

root.querySelectorAll "div"
let root = document.querySelector('#root'); root.querySelectorAll('div');
root.querySelectorAll ".outer"
let root = document.querySelector('#root'); root.querySelectorAll('.outer');
document.querySelectorAll "#root > .outer"
document.querySelectorAll('#root > .outer');
