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
what happens when I want to copy objects a lot
data = []
let i
for(i = 0; i < 1000000; i++){
data[i] = {"title": `product ${i+1}`, id: i}
}
for(j = 0; j < data.length; j++){
data[j] = tx(data[j])
}
Ready to run.
