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
Is comparing a string quicker or slower than comparing a boolean?
var sA = 'ben';
var sB = 'fox';
var sResult = '';
var bA = true;
var bB = false;
var bResult = false;
Ready to run.
