In this video I understand why we are doing this but not why its written like this. I spend more time looking up the unexplained things casually dropped in the videos than I do learning what the video is about.

This code is assigning it with an anonymous function expression.

11,405 PointsOhh. Haha ok. I actually figured it out shortly after but thanks again for your answer. You seem to know your stuff Steven. I was wondering as a matter of opinion, me brain feels like its folded in half before I 'get' it with a few of these concepts. Worried I may not be bright enough to do this half the time. Is this normal or is it if I am struggling now I may be in trouble?

Happy coding!
