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?")
}

You want to use the && conditional operator which requites both conditions you're testing for to evaluate to true.

var isAdmin = false;
var isStudent = false;

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

But since you're using a closing else statement, all that is doing is specifying what will happen after other conditions have failed, so all you need is else. :-)
