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 str = "hello world!";
var reg = /world/;
var browserSelect1 = function() {
// select correct chrome.tabs.query object based on browser
if (/(Google)/i.test(window.navigator.vendor)) {
return {"active": true, "currentWindow": true};
}
if (/(Opera)/i.test(window.navigator.vendor)) {
return {"active": true, "windowType": "normal"};
}
};
var browserSelect2 = function() {
// select correct chrome.tabs.query object based on browser
if (window.navigator.vendor.indexOf("Google") === 0) {
return {"active": true, "currentWindow": true};
}
if (window.navigator.vendor.indexOf("Opera") === 0) {
return {"active": true, "windowType": "normal"};
}
};
browser = undefined;
Ready to run.
