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
W = 100
iter = 20
function getArray(W) {
return Array.from({length: W}, () => Math.floor(Math.random() * 100000))}
// Function using Array.push.apply()
function pushApplys() {
arr1 = getArray(W);
for (let i = 0; i < iter; ++i) {
arr2 = getArray(W);
Array.prototype.push.apply(arr1, arr2);
};
return arr1;
}
// Function using Array.concat()
function concatArrays() {
arr1 = getArray(W);
for (let i; i < iter; ++i) {
arr2 = getArray(W);
arr1 = arr1.concat(arr2);
};
return arr1;
}
Ready to run.
