You have to check whether the string is equal to 'JavaScript' and alert 'You are correct' if it is.

So, you need an if statement:

if (answer === 'JavaScript') {
  alert ('You are correct');
}

You need to close the string inside the alert() method.

And you need to use === triple equals for the comparison.

I agree about the missing ' doh! But the == will work as well as they are both strings.

Agree in principle but in this context, i.e. passing the challenge, we need to use triple equals. It's part of the challenge tests. :wink: :+1:

Hi there,

You haven't closed the string in the first line; add a ' after the word 'language' and before the bracket.

Next, you want to see if the answer is 'JavaScript'. If it is, use the alert() method to prompt the user with the message 'You are correct'. Pass that string into the alert() method by putting it inside the brackets.

Steve.
