It looks like you just have an unnecessary semicolon after your if statement. There should be nothing (except space) between the closing parenthesis of the conditional statement, i.e.

(answer === 'JavaScript')

and the opening curly brace of the code to be applied if that condition is true, i.e.

{
  alert("You are correct");
}
