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

Posted by Noelle Chiavetta

How do I create an else clause with two variables equaling the same value?

Not sure how to add two variables to an else statement. I tried both && and putting a comma between the two variables. Is there something else that I might be missing?

Thanks!

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

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

The editor will accept this, because it asked for a final else clause, not another else if:

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

But if you want to do it that way, outside the editor:

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

I don't believe the else statement is supposed to hold two variables. (Note I'm a beginner too!) The else statement is supposed to be giving a "last" option if all the other options in the conditional statement is not true. I think for your else statement, it should go something like this:

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

Putting in isAdmin && isStudent = false is redundant.
