What is the format to test both?

I can't figure out how am I suppose to test both at the same time? Maybe, I should create two else statements.

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

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

It would be for what you want to do: 

var isAdmin = false;
var isStudent = false;

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

But to pass the challenge you just need to put :

var isAdmin = false;
var isStudent = false;

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

Indeed as Liam showed, remember the "else" statement is the fallback if no other condition above is met which is why it does not test for any conditions. If you wanted to test the condition, you would want to use an "else if" statement. For this program, however, "else if" isn't necessary because the program would already know if both isAdmin and isStudent was false, so using just "else" is be fine.
