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
Looks at the cost of creating an inner function
function fooWithBar(a, b) {
function bar(x) {
return x * b;
}
if (a < 3) {
return bar(a * 2);
}
return bar(a * 3);
}
function fooWithoutBar(a, b) {
if (a < 3) {
return (a * 2) * b;
}
return bar(a * 3) * b;
}
Ready to run.
