Add a final else clause to this conditional statement so that if the isAdmin variable and isStudent variables are both false an alert opens with the message "Who are you?"

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?')
}

Hi, Brigitt Arndt it's important to remember that, unlike if or else if, the else clause doesn't have a conditional followup.

} else {
    alert('Who are you?')
}

This would be fine.
