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. Here we realy test access to data, and except initialisation function.
<script>
// common data
var funct = {
get: function() {
return this._x
},
set: function(value) {
this._x = value
}
}
// first test data
var define = {
_x: 0
};
define.__defineGetter__('x', funct['get']);
define.__defineSetter__('x', funct['set']);
// second test data
var property = {
_x: 0
};
Object.defineProperty(property, "x", {
configurable: true,
get: funct['get'],
set: funct['set']
});
// third test data
var obj = {
_x: 0
};
//fourth test data
var proto = {
_x: 0
};
proto.prototype = {
get x() {
return this._x;
}, set x(value) {
this._x = value;
}
};
//five test data
var setter = {
_x: 0
};
setter.setX = function(value) {
this._x = value;
};
</script>
