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
// create an array with 2000 objects with some random data in them
const items = [];
for (let i = 0; i < 2000; i++) {
items.push({
id: i,
name: 'name' + i,
value: Math.random() * 100
});
}
let total = 0
function doSomeHandling(item) {
total += item.value;
}
Ready to run.
