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
Just quick test if reusing objects has perf benefits or not
const object = {
some: "object",
that: "has",
bunch: "of",
properties: 1,
}
const newPropVal = true
Ready to run.
