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
Check string interning capability
var str1 = concatenate(["as", "tr", "ing"]);
var str2 = concatenate(["ast", "ring"]);
var str3 = concatenate(["as", "tr", "N"]);
function concatenate(strings) {
let result = '';
for (const str of strings)
result = result + str;
return new String(result);
}
Ready to run.
