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 the performance of the jquery map versus a native for loop map
testArray = new Array(100);
for(var i = 0; i < 100; i++) {
testArray[i] = i;
}
function map(arr, fun) {
var ret = [];
for(var i = 0; i < 100; i++) {
ret.push(fun(testArray[i]));
}
return ret;
}
function double (x) {
return x*2;
}
Ready to run.
