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() {

},
set: function(val) {
this._prop = val;

});
var obj4 = {
_prop: 0

Object.defineProperties(obj4, {

get: function() { return this._prop },
set: function(val) { this._prop = val }
