Is it faster to use regex to detect a browser's os, or indexOf?
//methodology: ran the test 4 times and took the slowest time.
checkOSRegex = function(){
var os = navigator.platform;
return /[wl]in/i.test(os) ? /win/i.test(os) ? 'linux' : 'windows' : 'mac'; //slightly confusing, but 26% faster than
}
checkOSRegexStart = Date.now();
for(var i = 0; i < 1000000; i++){
checkOSRegex('MacIntel');
