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
class X { constructor() { this.name = "X" } }
class Y { constructor() { this.name = "Y" } }
const data = Array.from({ length: 1000 }).map(() => Math.random() >= 0.5 ? new X() : new Y());
Ready to run.
