Front End Web Development Techdegree Student 21,661 PointsWhy is function so hard to understand
I am trying to wrap my head around the video, i get that we need to check if the current category matches the string in get variable, to display the result but the function used like php array_categories and php array_rand are totally out of my mind, i tried reviewing this video for 3-4 times but failed. Can anyone break it down for me?

21,830 PointsAgreed. I've noticed in the last few videos that Alena seems to gloss over pretty complex ideas (at least for beginners). She seems to write out the code, and not break it apart and explain the different parts.

2,700 PointsRight. She just goes "so then we put this code in here"? WHY? Why are you choosing these specific things to type. We need a diagram or something.

9,499 Pointsyou need to explain more what you are not understanding. It sounds like you know what the purpose is, but what about the functions are you not getting? The return, why this function, what is the function doing?
