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
Measuring performance difference between calling Object.keys in a loop's conditional statement in every iteration and caching the value of Object.keys and looping over the value
const arr = new Array(10000).fill(1);
Ready to run.
