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
Comparing for(;;) to for..of to Array.forEach
let
test = [],
extraData = "Something to make the dataset larger;"
for (let value = 0; value < 1000; value++) {
test[value] = { value, extraData };
}
Ready to run.
