My own experiments&#x2F;experience shows that recrawls happen about 1&#x2F;3 as often and tend to lag a few days behind for JS content vs inlined&#x2F;delivered content.  It&#x27;s helped a little by dynamically delivering the sitemap data, but even that only speeds things up a little.<p>My guess is they&#x27;re putting about 1&#x2F;10th the effort into keeping things freshly indexed for JS, but may well be devoting 2x the resources vs directly received content.
