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
Do premature returns hurt performance?
Sucka!
<script>
function noreturn(a) {
if (a > .5) {
a += 1;
}
}
var a = .25, b = .75;
function premature_returnulation(a) {
if (a <= .5) {
return;
}
a += 1;
}
</script>
Ready to run.
