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
class Class1
{
method() {}
}
const instance1 = new Class1();
const objectWithDefaultPrototype = {
method() {},
}
const objectWithPrototypeOtherObject = {
__proto__: objectWithDefaultPrototype,
};
const objectWithChangedPrototype = {};
Object.setPrototypeOf(objectWithChangedPrototype, objectWithDefaultPrototype);
const REPEATS_COUNT = 1_000_000;
Ready to run.
