My page speed is suffering from unused javascript. I am using the Perfmatters plugin. IN Perfmatters, you can list the javascript for each page.

Is there a list somewhere of what each of these WordPress related javascripts do? Or is there a tool that will tell me which ones are unneeded on my site? I would do trial and error but that always backfires.

I’d love to know which of these I can just turn off.

Thanks!
