Datalog is a declarative database query language with roots in logic programming.

That's right, and even more holds: Syntactically, Datalog is a proper subset of Prolog!

In this tutorial, they use EDN, which is a subset of Clojure data instead.

Yes, I noticed. That's a very significant departure from Datalog syntax.

Is this a bot? Pretty good idea.

If you are wondering why you would want to dive in, let me offer another good reason: there is Datascript (https://github.com/tonsky/datascript), which puts a good subset of Datalog inside your client-side browser app.

I found it very useful for dealing with relational data in browser apps.

This seems like a really interesting page, unfortunately it's currently hard to consume on a smartphone: no mobile view and not possible to enable Reader Mode even on Firefox for Android :(

Reader mode is available in Safari (iOS). Maybe the github sources work for you? You'd miss out on the interactive parts, tho: https://github.com/jonase/learndatalogtoday/blob/master/reso...

To be fair, a big part of this page is the interactive exercises, which would be a nightmare to try to do on mobile anyway. So I can see why being compatible with mobile wasn't a big concern.

Well reading about this non interactively is still better than, well, not reading at all. I have vivid imagination!
