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
for (i = 0; i < 1000; i++) {
let textNode, spanElement;
textNode = document.createTextNode(i + " ");
spanElement = document.createElement("span");
spanElement.id = "foo";
spanElement.classList.add("bar")
spanElement.appendChild(textNode);
document.body.appendChild(spanElement);
}
Ready to run.
