Parse Error

Not really sure what is wrong with my code.

var isAdmin = false;
var isStudent = false;

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

I have also tried to add (isAdmin === false) + (isStudent === false), all I get is a parsing error.

Thanks.

Heya Dan!

The problem you're having there is that you've added a conditional to the else portion of your code. Else statements don't get conditions.

Things That Get Conditions in an If statement

  • if gets a condition
  • else if gets a condition
  • else does not get a condition.
if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
} else (false) { //<---- this right here... there should be no (false) condition
  alert('Who are you?');
}

The else part of the whole thing is there to execute when the if or else if does not meet the condition. It's the "plan B" so to speak. It's executing based on whether or not the condition after the if (or else ifs that are present) is met. Therefore, a condition somewhere before it has already been evaluated and thus is not needed after an else :).

Hope that helps!

Cheers,

Awesome, thank you. Can't believe I didn't catch that.
