Benchmark: classList.contains vs. Set vs regex

HTML Preparation code:

<div id="foo" class="bang zoom boom dang kazam hallabalooza foo didgeridoo bar baz ding dong skill skull bip bop"></div>

Script Preparation code:

var test_element = document.getElementById("foo");

Tests:

Use hasClass shorthand
function hasClass(element, classes) { var classesSet = new Set(element.classList) classes = classes.split(' '); for (var i = 0; i < classes.length; i++) { if (!classesSet.has(classes[i])) { return false; } } return true; }; hasClass(test_element, "bang zoom boom dang kazam hallabalooza foo didgeridoo bar baz ding dong skill skull bip bop");
Use classList
test_element.classList.contains("bar"); test_element.classList.contains("baz");
Use classname match
test_element.className.match('bar'); test_element.className.match('baz');
