Final 'else' statement, just not working for me.

I've also tried

else (isAdmin === false === isStudent) {

 alert("Who are you?");

}

script.js 
var isAdmin = false;
var isStudent = false;

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
}
else( isAdmin === false && isStudent === false){
  alert("Who are you?");
}

Timothy, the last else statement does not need any conditions to be checked. You can omit the last set of parens and test conditions. It's basically saying that it knows everything else failed the tests, so do this last thing by default.

if (isAdmin) {
// do something
} else if (isStudent) {
// do another thing
}
else {
// do this because the others failed
}

Hey Timothy,

An else statement can't have any conditionals. All the conditions are checked with the if and the else if statement, so if the code was to reach the else statement, it means that everything has failed and this is what should be done now.

else {
  alert("Who are you?");
}

Hope this make sense. Keep Coding! :dizzy:
