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
Comparing the performance difference of varied jQuery 1.7 selectors.
This test page contains some dummy HTML (from html-ipsum.com) just to give the page some weight, make the selectors work a little bit.
Note that the "Tag" selector is selecting a tag that happens to be unique in the page just to be fair.
