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 different access method to an object property
<script>
var acc = 0,
funct = {
get: function() { return this._x; },
set: function(value) { this._x = value; }
},
obj = { _x: 0 };
//obj.__defineGetter__('a', funct['get']);
//obj.__defineSetter__('a', funct['set']);
Object.defineProperty(obj, "b", {
configurable: true,
get: funct['get'],
set: funct['set']
});
obj.prototype = {
get c() { return this._x; },
set c(value) { this._x = value; }
};
obj.getX = function() { return this._x; };
obj.setX = function(value) { this._x = value; };
</script>
