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
Showing the performance difference between a for..in loop using hasOwnProperty and without.
var obj = {
somekey: 'somevalue',
somekey2: 'somevalue',
somekey3: 'somevalue'
};
Ready to run.
