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
A brief comparison of some JavaScript templating engines on a short template: 6 header tags, and 10 list items.
Note: When adding a new test, please ensure that your test returns the same HTML string (or equivalent DOM fragment) as the others.
