Try and hit "Shift 1000 items (with reorder)" multiple times in a row and see the performance: https://frzr.js.org/example/index.html

I challenge you to do the same in your favourite framework x ;)

The demo link goes to a secure https url, but the frzr JS is pointing to the non-secure http url and therefore not loading.

Suggest changing JS src url to just //frzr.js.org/dist/frzr.min.js (to load either, based on current scheme) or https.

Fixed now, thanks! https://frzr.js.org/example/index.html
