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
Testing various techniques for creating getters / setters in JavaScript.
<script>
var obj = {
_prop: 0
}
var obj1 = {
_prop: 0,
getProp: function() {
return this._prop;
},
setProp: function(value) {
this._prop = value;
}
};
var obj2 = {
_prop: 0,
get prop() {
return this._prop;
},
set prop(value) {
this._prop = value;
},
};
var obj3 = {
_prop: 0
}
Object.defineProperty(obj3, "prop", {
get: function() {
return this._prop;
},
set: function(val) {
this._prop = val;
}
});
var obj4 = {
_prop: 0
}
obj4.__defineGetter__("prop", function() {
return this._prop;
});
obj4.__defineSetter__("prop", function(val) {
this._prop = val;
});
var obj5 = Object.create(obj3);
obj5._prop = 0;
var obj6 = Object.create(obj4);
obj6._prop = 0;
