Favorite Website Analysis.

So as you know I decided to do my speech for Crunchyroll. After analyzing the website's source coding, I looked and realized they use HTML for the skeleton and java script for most of the actual website. I don't know much about coding but I do know that java script runs most animations that have to do with any website, minus pictures, which leads me to believing that because it's such a stuffed website, most of the items on there are likely java so it can be smooth and transitional with things like "New Anime Updates" and "Forum Posting" and such.
