The else conditional is like safety measure that you implement when you know a certain conditions will fail but you still wanna achieve some result, right? Now regarding your code, just remove the (isAdmin, isStudent = false) -- it'll throw a syntax error, thats why you need to remove it. Also, default values of isStudent and isAdmin is false so you dont have to worry about 'em.
Here is the code in case you still get stucked:
var isAdmin = false;
var isStudent = false;
if ( isAdmin ) {
alert('Welcome administrator');
} else if (isStudent) {
alert('Welcome student');
} else {
alert('Who are you?')
}
