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
A quick test to see if some sort of caching of function results can improve performance.
<script>
// Normally I'd wrap this in an anonymous function.
var _cache = {};
function CacheTest(a, b) {
if (!_cache[result]) {
var result = a + b;
_cache[result] = result;
}
return _cache[result];
}
function NoCacheTest(a, b) {
return a + b;
}
</script>
Ready to run.
