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
Performance difference between calling method that was declared into a Javscript object, and calling the same method that was declared outside of the object with protoype keyword

<script>
var X, Y, x, y, i, intNow;
X = function() {};
X.prototype.message = function(s) {
var mymessage = s + "";
}
X.prototype.addition = function(i, j) {
return (i * 2 + j * 2) / 2;
}
Y = function() {
this.message = function(s) {
var mymessage = s + "";
}
this.addition = function(i, j) {
return (i * 2 + j * 2) / 2;
}
};
</script>
Ready to run.
Test | Ops/sec | |
---|---|---|
Y method is declared into the Javscript object class |
| ready |
X method is declared outside class by using protoype keyword |
| ready |
