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
How much does returning a value slow a function down?
<script>
function noReturn(val) {
val = val - 0;
}
function doesReturn(val) {
val = val - 0;
return val;
}
</script>
Ready to run.
