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
const headers = Array(10).map(_ => (Math.random() * 100).toString());
const addHeaders = Array(10).map(_ => (Math.random() * 100).toString());
const rows = Array(100_000).map(_ => {
const obj = {};
headers.forEach(header => {
obj[header] = Math.random();
});
});
const scims = Array(100_000).map(_ => {
const obj = {};
addHeaders.forEach(header => {
obj[header] = Math.random();
});
});
Ready to run.
