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

var width = 500;

var a = b = [];
for(var i = 0; i < height; i++) {
var a[i] = [];
for(var j = 0; j < width; j++) {
a[i][j] = [];
}
}
for(var i = 0; i < width * height; i++) {
b[i] = [];
}
</script>
Ready to run.
