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
function immutable(obj, key, value) {
return {...obj, [key]: value}
}
function mutable(obj, key, value) {
obj[key] = value;
return Date.now();
}
function mutableCreateObject(obj, key, value) {
obj[key] = value;
return {};
}
Ready to run.
