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
var samples = 120000;
function t1(){
var arr = [samples];
var arr2 = [];
arr2.push(...arr);
}
function t2(){
var arr = [samples];
var arr2 = [];
for(var i=0;i <= arr.length;i++){
arr2.push(arr[i]);
}
}
function t3(){
var arr = [samples];
var arr2 = [];
var length = arr.length;
for(var i=0;i <= length;i++){
arr2.push(arr[i]);
}
}
function t4(){
var arr = [samples];
var arr2 = [];
for (let i in arr) { arr2.push(arr[i]); }
}
Ready to run.
