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:

) {
return true;
}
return false;
}
function inBounds2(rect, canvas) {
if (
rect.left > canvas.left + canvas.width ||
rect.top > canvas.top + canvas.height ||
