Using an OR statement

It doesn't work in the challenge but would an the OR statement work as well as &&

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

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

no, OR ( || ) and && are different than each other, when we use OR , the code will execute if one of our conditions are true, but when we use && (and) ALL the conditions MUST be true.

The "else" case is is very simple, there are no arguments or logic to be specified. Just else. That takes care of any other possibilities there might be, regardless of the amount of possibilities. 

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