else if question

I'm not understanding the error message I'm getting, is the alert in the wrong line?

var isAdmin = false;
var isStudent = true;

if ( isAdmin === false ) {
    alert('Welcome administrator');
}   else if ( isStudent === true ) {      
    alert("Welcome student");

Your testing logic doesn't match the messages. If "isAdmin" is false, you probably don't want to say "Welcome administrator".

Also, while this won't affect passing the challenge, you don't need to compare boolean values to true or false. Just naming them is enough, or inverting them (with "!") when you need the opposite.

For example, "if (isStudent)" is the same thing as "if (isStudent === true)".

It won't get to the 'else if' if the main 'if' evaluates. isAdmin is set to false. You ask if isAdmin is false. It is, so it only does the alert in there.
