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
This is a comparison of different promise libraries, performing the most basic tasks of creating a promise, adding a then handler and then resolving the promise.
Removed SLOW laissez-faire Removed avow which has bad code for checking module
