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
a1 = [];
a2 = [];
for (i = 0; i < 1000; i++) {
var o1 = {
x: "vx",
y: "vy"
};
var o2 = {
x: "vx",
y: "vy"
};
Object.freeze(o2);
a1.push(o1);
a2.push(o2);
}
Object.freeze(a2);
Ready to run.
