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
document.links vs document.getElementsByTagName
I realize that document.getElementsByTagName will bring in both <a href="#"></a> and <a name=""></a>, while document.links will only return <a href="#"></a>; so this may not be a fair comparison.
<a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a>Ready to run.
