Challenge Makes No Sense To Me

The coding doesn't seem to be the problem. It's what they are asking of me that is the problem. For example the challenge is:

Set the variable 'anonymousFunction' to be an anonymous function without any code to be executed.

So I this code:

var anonymousFunction = function() {});

It's an anonymous function isn't it?

Thanks

If you haven't figured this out yet, maybe this will help:

As the article says in that link, "Those two little brackets cause everything contained in the preceding parentheses to be executed immediately."

So the answer is to add () to line 20, immediately before the ;

It looks like you have an extra ")". Try this:

var anonymousFunction = function() {};

Thanks so I managed the first task but now they want me to execute it. Here is my code:

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

For some reason it isn't passing. As I am dyslexic I'm having real hard time understanding what they want me to do. It would be great if they went a little more in-depth.

I think they want you to execute it using the variable you assigned it to. Like this: anonymousFunction();

The way you have it written would execute the function and assign the return value to anonymousFunction. This can be very handy (if you are interested, try a google search for javascript closures), but with your current code, you are essentially just assigning anonymousFunction a value of "undefined".
