If you use the JQuery migrate tool as I do (see below) it reports the following:
jquery-migrate-3.4.1.js:136 JQMIGRATE: jQuery.isArray is deprecated; use Array.isArray
isArray is still supported in JQ3.7.1 - but in future releases it will likely be removed. I imagine pickadate is using other deprecated JQ functions - but this is the only one I ran across
