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
Compare slice + join vs. join apply
<script>
function testSlice() {
var args = [].slice.call(arguments, 0);
return args.join('###');
}
function testJoin() {
return [].join.call(arguments, '###');
}
</script>
Ready to run.
