jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
<ul id="test"></ul>
var ul = document.querySelector("#test");
for (var i = 0; i < 1000; i++) {
var li = document.createElement("li");
li.textContent = "List Item " + i;
if (i % 2) {
li.setAttribute("data-component", "list-item");
li.className = "list-item my-other-class";
}
ul.appendChild(li);
}
ul.innerHTML = "";
Ready to run.
