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
Test native private property access versus non-private property access. Both are accessed through instance methods for fair comparison. Both properties are initialized with Math.random() to avoid optimization.
class Test {
#priv = Math.random();
pub = Math.random();
getPriv() {
return this.#priv;
}
getPub() {
return this.pub;
}
}
Ready to run.
