Test runner

Ready to run.

Testing in
TestOps/sec
Classic function
function getCookie(cname) {
    var name = cname + "=";
    var ca = cookieString.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

identsToCheck.forEach(function(el){
   var test = getCookie(el);
});
ready
Using RegEx
function getCookie(name) {
   var match = cookieString.match(RegExp('(^| )' + name + '=([^;]+)'));
   return match ? match[2] : ''
}

identsToCheck.forEach(function(el){
   var test = getCookie(el);
});
ready
Using RegEx with word boundary
function getCookie(name) {
    var r = cookieString.match("\\b" + name + "=([^;]*)\\b");
    return r ? r[1] : null;
};

identsToCheck.forEach(function(el){
   var test = getCookie(el);
});
ready
Using split
function getCookie(name) {
	var value = "; " + cookieString;
	var parts = value.split("; " + name + "=");
	if (parts.length == 2) return parts.pop().split(";").shift(); return "";
	}

identsToCheck.forEach(function(el){
   var test = getCookie(el);
});
ready
