730 Pointshow do I include TWO false variables in an ELSE statement?
var isAdmin = false; var isStudent = false;
if ( isAdmin ) { alert('Welcome administrator'); } else if (isStudent) { alert('Welcome student'); } else ( isAdmin isStudent) {alert("Who are you?");}
var isAdmin = false;
var isStudent = false;
if ( isAdmin ) {
alert('Welcome administrator');
} else if (isStudent) {
alert('Welcome student');
} else ( isAdmin isStudent) {alert("Who are you?");}

An else statement will not have a following set of parentheses with a condition in them. Instead, it just has a code block following it. Also, since you have already checked to see if isAdmin and isStudent are true in the previous if and else if statements you do not need to recheck that they are false. Therefore, if you remove the ( isAdmin isStudent )
from your code it will be properly formatted:
else {alert("Who are you?");}
However, if you do want to test for two conditions in one statement you can use the logical and (&&) or logical or (||). In this case you would need to change the else to another else if since else cannot make use of an additional condition (it is kind of like a finally block). Here is how it would be coded for these two conditions:
else if ( !isAdmin && !isStudent ) {alert("Who are you?");}
This states that you would like to print an alert if isAdmin is false AND if isStudent is false.

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