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
let a = {
"icon": {
},
"font": {
},
"background": {
},
"border": {
},
"borderRadius": {
}
};
function isEmptyObject(object ) {
for (const key in object) {
if (Object.prototype.hasOwnProperty.call(object, key)) {
return false;
}
}
return true;
}
Ready to run.
