Inevitably, I'm trying to improve our Magento 2.3.0 Pagespeed score. Most of the damage is being done by the excess of unneeded/unwanted js files.
Is there any simple way to remove js such as calendar.js, tooltip.js etc? It appears tooltip.js is loaded by jquery-ui.js but I can't find where calendar is loaded using grep, any suggestions please?
I expect deleting/renaming the unwanted js files will result in errors at best and a non functioning website at worst? Thanks
