Add a final clause 101 objective

I first tried linking them with a + sign and went along till i tried this. Any ideas?

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

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

Kaleb,

Here is the correct code. var isAdmin = false; var isStudent = false;

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

}

Hi Kaleb,

To start with, the structure of an if else if statement can only contain 1 if and 1 else. In between as many else if as you want. The logic will try each steps and execute only if it is true.

if (true or false) { if it was true do this (if not got to the next else if check); } else if (true or false) { if it was true do this (if not got to the next else if check); } else { if not of the above were true do this; }

So in this example we check if 1: are you admin? 2: are you student? 3: if you not admin nor student ask who we are.

I hope it will make sens and you'll get the logic instead of having a direct answer to the challenge :)
