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
function directNotEmpty(s) { return s.length > 0 }
function keysNotEmpty(s) { return Object.keys(s || '').length > 0 }
var bigString = "several base64-encoded PNG images".repeat(1000)Ready to run.
| Test | Ops/sec | |
|---|---|---|
| direct (lodash minus one test) | | ready |
| via Object.keys length | | ready |
You can edit these tests or add more tests to this page by appending /edit to the URL.
