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
const maybeNumbers = [];
for (i = 0; i < 1000; i++) {
if (Math.random() > 0.5) {
maybeNumbers.push(10 * Math.random() | 0)
} else {
maybeNumbers.push(null);
}
}
Ready to run.
