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 format = {
weekday: 'long',
month: 'long',
day: '2-digit',
};
const now = new Date();
const sharedDateTimeFormat = new Intl.DateTimeFormat('en-US', format);
const sharedDateTimeZeroFormat = new Intl.DateTimeFormat('en-US');
Ready to run.
| Test | Ops/sec | |
|---|---|---|
| Intl.DateTimeFormat with formatting | | ready |
| toLocaleString with formatting | | ready |
| Intl.DateTimeFormat reused with formatting | | ready |
| toLocaleTimeString no formatting | | ready |
| Intl.DateTimeFormat reused no formatting | | ready |
