You should not change the condition in the if-statement.

var isAdmin = false;
var isStudent = true;

if ( isAdmin ) { // dont change this
    alert('Welcome administrator');
} else if ( isStudent ) { // here create the 'else if' to check if 'isStudent' is true
    alert('Welcome student'); // then create the alert
}

Hiya there! There are few bugs in your code. First, you changed the code that came as a default to the challenge. Dont do that unless challenge explicity ask you to. Second, "else if" block takes a boolean expression to evaluate, which you didnt provide any, and when it returns true, it executes the code inside the code block. Here is how your code needs to look like:

var isAdmin = false;
var isStudent = true;

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome Student');
}

You aren't checking anything in your else if clause. Else if conditionals need a clause to check for the code after it to fire. It appears you've maybe confused else and else if.

Hi Mihia,

You can remove the "if ()" on your condtion if you don't have any additional condition. We only use them if we intended to have at least multiple condition..

see here:

if ( isStudent = true) {
    alert('Welcome administrator');
}else {
    alert('Welcome student');
}

Here are example of using if.. else if.. else if. else on a scenario where an actor audition. (just for fun)

if (actor = 'dance') {
 alert('user can dance! that will do');
} else if( actor = 'sing') {
 alert('actor can't dance but he surely can sing. that will do');
} else if(actor = 'act') {
 alert('actor can't dance, can't sing but he sure can act. that will do');
} else {
 alert('sorry actor didn't pass the audition');
}

Hope this help!

Owa
