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
Test the speed of a for loop when incrementing vs decrementing.
function loopInc() {
for(var i = 0; i < 1000; i++);
}
function loopDec() {
for(var i = 1000; i; i--);
}
Ready to run.
