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
Moving the object instantiation outside prep block.
function T() {
this.name = 'T';
}
T.prototype.myMethod = function(i) {
if (i == 20000) {
console.log('Hey ' + this.name);
}
};
function Tt() {
this.name = 'Tt';
this.myMethod = function(i) {
if (i == 20000) {
console.log('Hey ' + this.name);
}
};
}
function fact() {
var inst = {};
inst.name = 'fact';
inst.myMethod = myMethod;
function myMethod (i) {
if (i == 20000) {
console.log('Hey ' + inst.name);
}
};
return inst;
}
