What is the name of the js for the featured category slider?

On my homepage, I’m using the featured category slider (though I’m only using it with one image because I like how it looks, but I don’t want it sliding).

Currently I have javascript deferred, and in practice that means I have a blank space on my homepage for about five seconds on load. I want to add this JS to the exception list so it gets loaded immediately, but I can’t figure out which it is – can you tell me?

The page I need help with: [log in to see the link]
