JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Add a Final Else Clause

"else if" clause error.

Hey fellow Treehouse Enthusiasts!

... I'm having difficulty getting past the next stage here. My code is getting rejected on this challenge because I haven't added an "else" statement at the end of my code?

I'm kind of confused & if some kind soul would just take a look over my code I'd be much appreciated.

Thanks!

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

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
} else if (isAdmin = false) {
     alert('Who are you?');
} else if(isStudent = false) {
     alert('Who are you?');
}

Well, you haven't added a final else clause. You added two additional else if's to the end of your if block. Simply remove the last two else if's and instead say

} else { alert('Who are you?'); }

I have the following coded in the challenge & it is telling me that I have a syntax error but I can't figure it out.

var isAdmin = false; var isStudent = false;

if ( isAdmin ) { alert('Welcome administrator'); } else if (isStudent) { alert('Welcome student'); } else if (isAdmin = false) { alert('Who are you?'); } else (isStudent = false) { alert('Who are you?'); }

I have the same code he had, except I have included the else clause.

You're getting a syntax error because else (isStudent = false) is not proper syntax. The else is used to catch everything else that wasn't caught by the conditionals of the if and else if's. So you shouldn't have a conditional next to the else statement.

That being said, once you have checked isAdmin and isStudent, everything else should fall into the else. So you should have something like this:

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