I am trying to do boolean conditional statement and it does not seem to be working

Here is the code. It keeps telling me there is an error. var isAdmin = false; var isStudent = false;

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

thanks so much

this is what the error says Did you add a final else clause at the end of the conditional statement?

Hi Monica,

Your last conditional statement is a bit redundant. Try:

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

ok thanks! what is the difference between the else and the else if clause?

Not much. Just else would mean, Do the following things if the previous conditional is falsey. An else if says, Do the following things if the previous conditional is falsey and if this conditional is true.

The way you had it would work... it's just a bit redundant. Let me know if that's not clear :)
