Benchmark: window.getComputedStyle vs. getBoundingClientRect vs. window.getComputedStyle without getters

HTML Preparation code:

<div id="foo"></div>

Tests:

getComputedStyle
var i = 5000; while (i--) { checkDisplay('foo'); } function checkDisplay(id) { return window.getComputedStyle(document.getElementById(id), null).getPropertyValue("display") === "none"; }
getBoundingClientRect
var i = 5000; while (i--) { checkDisplay('foo'); } function checkDisplay(id) { return document.getElementById(id).getBoundingClientRect().width === 0; }
getComputedStyle without getters
var i = 5000; while (i--) { checkDisplay('foo'); } function checkDisplay(id) { return window.getComputedStyle(document.getElementById(id), null); }
getElementById
var i = 5000; while (i--) { checkDisplay('foo'); } function checkDisplay(id) { return document.getElementById(id); }
