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
which works best for checking if an object with a particular id has been received before?
const itemsArray = [];
const itemsSet = new Set();
for (let i = 0; i < 5000; i++) {
itemsArray.push({ id: i })
itemsSet.add(i)
}
Ready to run.
