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:

const str = `There are 'many' variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some 'form', by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need 'to' be sure there isn't anything embarrassing 'hidden' 'in' 'the' middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true 'generator' on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or 'non-characteristic' 'words' etc.`Ready to run.
