Research direction
Read the linked Datomic Outer Joins article and compare its entity-navigation and extension-function approaches with the Datascript API. Check whether Datascript provides a maybe function or another documented mechanism; done means documenting a supported approach or clarifying that full outer joins are unavailable.

Description
Hi there,
I am trying to evaluate if Datascript is the right tool for a problem I'm trying to solve.. and I was wondering how I might accomplish a (full) outer join or equivalent.
For Datomic I found the following article, which mentions two approaches (entity navigation or extension function), and I was wondering if either of these would work with Datascript:
https://support.cognitect.com/hc/en-us/articles/215581518-Outer-Joins
For example, regarding the extension function approach, I didn't find any reference to a maybe function in the Datascript api.
Thanks!
