why doesnt this work?

var isAdmin = false; var isStudent = false;

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

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

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

Hi, when using else your saying if everything previously checked is false do this so no condition is required (the bit between the brackets).

p.s it still won't work as you need a question mark at the end of 'who are you' because of the question.

The else portion of an if...else statement doesn't get a condition. 

if ( condition1 ) {
 // code to run when condition1 is true
}
else if ( condition2 ) {
 // code to run when condition 2 is true
}
else {
 // code to run when conditions are false
}

In your code, you need to remove the condition from the else.

} else {

You don't need to put parenthesis in else, so take all that off, and don't forget question mark (?) in alert. Good luck!
