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
How slow is the use of arguments
?
<script>
function a() {
return [arguments[0], arguments[1], arguments[2], arguments[3], arguments[4], arguments[5], arguments[6], arguments[7], arguments[8], arguments[9]];
}
function b(arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9) {
return [arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9];
}
function c(arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9) {
if (arg4 === undefined) {
return [arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9];
}
return [arguments[0], arguments[1], arguments[2], arguments[3], arguments[4], arguments[5], arguments[6], arguments[7], arguments[8], arguments[9]];
}
</script>
