How to optimize JS?

Hey, hoping someone can help me with this. I don’t really know too much about speed optimization other than looking at this and GT Metrix and what it is telling me to edit.

Is it possible to edit the JS on this page? Will moving them to the footer help? I don’t get why the content breakdown show a significant portion of it being JS?


The results I see are all warning about JS? [url=][/url]

Any help would be appreciated!
