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>
var Base2 = {
base: 2,
exponent: function(power) {
var result = 1;
for (var i = 0; i < power; i++) {
result *= this.base;
}
return result;
},
exponentCacheBase: function(power) {
var result = 1;
var base = this.base;
for (var i = 0; i < power; i++) {
result *= base;
}
return result;
}
};
</script>
Ready to run.
