Anonymous Functions

Can anyone help with this challenge:

On about line 18, make the anonymous function with the code 'window.didExecute = true' execute.

<script>
      var anonymousFunction = function() {

      };

      (function () {
        window.didExecute = true;
      });
    </script>

thanks.

You need to concentrate on this part of the code:

(function () {
    window.didExecute = true;
});

Your task is to create what is known as IIFE (immediately-invoked function expression).

This code is a function, but because it's an anonymous one, you can't execute it by calling its name, and it won't get executed on its own. However, it's still a function and same rules apply. To call a function, you'd add the parentheses after its name.

So, all you're supposed to do is add () before the final semicolon.
