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

```
let sp = 100000;
const numbers = new Int32Array(sp);
for (let i = 0; i < sp; i++) {
numbers[i] = (Math.random() * 0x100000000) & 0xffffffff;
}
const ints = new BigInt64Array([...numbers].map((x) => BigInt(x)));
const operations = [
(a, b) => a + b,
(a, b) => a - b,
(a, b) => a * b,
(a, b) => b == 0 ? b : a / b,
(a, b) => b == 0 ? b : a % b,
];
let op = 0;
function popNumber() {
return numbers[--sp];
}
function pushNumber(number) {
numbers[++sp] = number;
}
function popInt() {
return ints[--sp];
}
function pushInt(int) {
ints[++sp] = int;
}
```

Ready to run.
