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

7,709 PointsFor anyone who is still confused, all you need to do is:
var anonymousFunction = function() {};
(function () {
window.didExecute = true;
}) ();

omg guys we've been breaking our heads for nothing loll All it asks is to make the self executing function execute which all it was missing were the parentheses, it never said to make the self executing function execute the anonymousFunction variable! hahah Seems a bit of a mixup of explanation and variable confusion. I was stuck on this for a good hour or so! XD Hope this helps anyone confused about it.

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

Kelvin Yu
2,554 PointsIn the video prior to the this task, Jim placed 2 random arguments in the empty parenthesis to immediately pass the anonymous function like so:
(function () {
var a, b, c;
// ...
console.log('from anon function')
})(arg1, arg2)
My question is, why would this not work in the task? Also, what is the difference when using empty vs. filled parenthesis in an anonymous function?

24,380 PointsKelvin, I struggled for awhile with this challenge question and after figuring it out, had (have) the same questions as you. I think further elaboration/clarification is required in the video when that topic is introduced. Particularly what role the arguments (or lack of arguments) play in an anon function when it's used as an object (as per your screenshot).

24,380 PointsKelvin, I share same questions as you. Struggled for awhile with challenge question. I believe the role of args in an anon function used as an object could benefit from further elaboration in the video.

10,910 PointsI second that, I passed in (1, 'hello') like Jim did at the end of video, but instead the answer is to just put () - I'm none the wiser as to why that works.
Jim Withington
12,025 PointsI wondered the same thing: if empty parentheses works, why does passing it some sort of value not work?

Carlos Eduardo Bruno Pereira
Courses Plus Student 6,928 Pointsdon't forget the first open parenthesis before "anonymousFunction". I saw that you didn't put it there.
Eldy Voon
3,812 PointsI don't get it
Carlos Eduardo Bruno Pereira
Courses Plus Student 6,928 Pointssorry, I've wrong. Actually, you don't need to put the 'anonymousFunction' before the function itself. On line 18, the function is already there, just put the open and close parenthesis at the end of it. Like this: (function () { window.didExecute = true; })(); see? No 'anomFunction' before it. Try it, and if it doesn't work, sorry but I don't know what else it can be.
Josh Flowers
7,010 PointsEldy Voon, Carlos is correct. All you need to do is add a set of empty parenthesis as there are no arguments to pass into it.

32,286 PointsWhat it worked for me in the 2nd task is the below:
(function () {
window.didExecute=true;
})()(anonymousFunction);

Courses Plus Student 2,858 PointsThis is worked (function () {
window.didExecute=true;
})()();
