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
According to MDN, toLocaleString
has to run a lookup each time its called. In cases where its called many times, it's better to create a Intl.NumberFormat
object and use its format method. This tests that claim.
const formatter = new Intl.NumberFormat('en-US')
Ready to run.
