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
Want to test the effects of using variable values that must be implicitly type-coerced versus explicitly coercing them.
<script>
var num_1 = 10;
var num_2 = "10";
var result_1, result_2, i;
</script>
Ready to run.
Test | Ops/sec | |
