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
We have a default value for a variable which could be a function. Is it faster to check if it is a function and don't call it if not or is it faster to call a noop function?
const maybeFunction = null
const noop = () => {}
Ready to run.
