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 a,b='';
function x() {
for(a=0;a<20;a++)
b+=a;
}
var e,f='';
function z() {
for(window.e=0;window.e<20;window.e++)
window.f+=window.e;
}
function y() {
var c,d='';
for(c=0;c<20;c++)
d+=c;
}
</script>
Ready to run.
