Hi, I am have added correctly the first two steps and am tripping up on the third. The final else statement to represent if both answers for administrator and student are false then the alert for 'who are you' value should be returned.
Where am I going wrong? Ali
var isAdmin = false; var isStudent = false;
if ( isAdmin ) { alert('Welcome administrator');
} else if (isStudent) { alert('Welcome student');
} else ({isAdmin} + {isStudent}) { alert('Who are you?');
var isAdmin = false;
var isStudent = false;
if ( isAdmin ) {
alert('Welcome administrator');
} else if (isStudent) {
alert('Welcome student');
} else ({isAdmin} + {isStudent}) {
alert('Who are you?');
}

16,266 PointsThe else block is the final block in a chain of if-else-if-else statements. If none of the prior if or else-if statements execute, then the else block will execute. So you shouldn't have any conditions in the else block.
The general structure is like this -
if(someCondition) {
// do this
}
else if(someOtherCondition) {
// do this instead
}
else {
// nothing above matched, so do this
}
Fix your else block to remove the condition -
else ({isAdmin} + {isStudent}) {
alert('Who are you?');
}

Courses Plus Student 1,359 PointsThis didn't help me. I don't know what the correct final condition should be, I get a syntax error. I've tried these. The more I guess the more confused I get as this is the first time I've tried this in JavaScript. Can you tell me what the final condition should be please?
} else (=true) { alert('Who are you?'); }
} else { alert('Who are you?'); }
} else ({isAdmin} + {isStudent}) { alert('Who are you?'); }
