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
Read access speed for different array containers.
var W = 100;
var size = W * W;
var typed = new Int32Array(size);
crypto.getRandomValues(typed);
var array = [...typed];
var nested = [];
for (let n = 0; n < W; n++) {
nested.push(
[...typed.slice(n * W, (n + 1) * W)]
);
}
var acc = 0;
Ready to run.
