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 a = new Float32Array(1e8);
a[0] = NaN;
const NAN_VALUE = new Float32Array([-12345.6789])[0];
a[1] = NAN_VALUE;
Ready to run.
