4,247 PointsHow to add multiple else clauses
Hello, I'm trying to finish this code challenge where I'm asked to pop up alert box with "who are you" after both conditions are false. Both conditions are isAdmin and isStudent, both false. How do I write the else statements? I keep getting syntax/parse errors.
var isAdmin = false;
var isStudent = false;
if ( isAdmin ) {
alert('Welcome administrator');
} else if (isStudent) {
alert('Welcome student');
} else (isadmin) {
alert('Who are you?');
}

else clauses cannot take any conditionals. The isAdmin is being checked in the if clause. The isStudent is being checked in the else if clause. If neither of these two clauses are triggered (return true) then the else clause will be executed by default. So, you just need to delete the conditional check you placed in the else clause and you're good to go.
So, just to clarify, an else statement will never and cannot ever take a conditional. You would do all the checks in the if statement, and if needed the else if statements. The else statement will always and only execute when all other checks fail (return false).
Hope that helps.
Keep Coding! :)

4,247 PointsThank you. Am I correct in thinking that the () was the problem? In other words, () tells the computer that I have conditions I need executed? I simply deleted those and it passed.
Ex: else { alert('Who are you?'); }
