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
Non-primitive objects defined on the prototype are shared and result in much higher speed.
function Size(width, height) {
this.width = width;
this.height = height;
};
Size.prototype.area = function() {
return this.width * this.height;
};
function Size2(width, height) {
this.width = width;
this.height = height;
this.area = function() {
return this.width * this.height;
}
}
Ready to run.
