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
is
var a = 1, b = true, c = "c", d = [], e = {}, u;
function isUndefined(value) {return typeof value === 'undefined';}
function isEqUndefined(value) {return value === undefined;}
Ready to run.
