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 type="module">
const {flatten} = await import ("https://cdn.jsdelivr.net/npm/lodash-es@4.17.21/lodash.min.js");
window.flatten = flatten;
</script>
const arr1 = [0, 1, 2, [3, 4]];
const reduceFlatten = (arr) => arr.reduce((flat, next) => flat.concat(next), []);
Ready to run.
