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
o1 = [];
o2 = [];
o3 = [];
for (var i = 0; i < 100; i++) {
o1.push(i)
o2.push(i)
o3.push(i)
}
Object.freeze(o2);
Object.seal(o3);
function doAnything(x) { }
Ready to run.
