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 speed-wise is relying on prototype
var Obj = function () {};
var obj = Obj.prototype = {
fa: function (a) { return this.fb(a);},
fb: function (b) { return this.fc(b); },
fc: function (c) { return c + 1; }
};
var cache = [];
var add2Cache = function (obj) {
cache.push(obj);
return obj;
};
cache = [];
Ready to run.
