The following line:

( isAdmin + isStudent === false );

is breaking up your if-then-else statement flow as it is after your closing } for the if statement above that line and you probably intended for that line to also be run with the line above it. Your if-then-else logic should look like so:

if ( isAdmin ) {
    // do something if isAdmin
} else if ( isStudent ) {
   // do something if NOT isAdmin but isStudent
} else {
   // do something if NOT isAdmin and is NOT isStudent
}

I think you are wanting to do this:

const isAdmin = false;
const isStudent = false;
let message;

if ( isAdmin ) {
   message = 'Welcome admin';
} else if ( isStudent ) {
   message = 'Welcome student';
} else {
   message = 'Access denied';
}

I hope this helps....
