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
Emptying an array and check if GC has some influence in it.
var arr = [];
for(var i = 0, len = 25 * 1024 * 1024; i < len; i++) // runs 25 to 100 times = some mb
{
arr.push('a');
}
Ready to run.
