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
<script>
// Populate the base array
var arr = [];
for( var i = 0; i < 1000; i++ ) {
arr[i] = 'value' + i;
}
function someFn (ix) {
return ix * 5 + 1 / 3 * 8;
}
</script>
Ready to run.
