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
To test if wrapping document.querySelector is faster then passing the selector to jquery as normal.
<article class="something"></article>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>Ready to run.
| Test | Ops/sec | |
|---|---|---|
| $(querySelector) | | ready |
| $('selector') | | ready |
| $('selector').find('something') | | ready |
You can edit these tests or add more tests to this page by appending /edit to the URL.
