Backbone and Underscore

https://github.com/automattic/_s ?

No. Would be pretty neat if _s was a part of core though. I mean the javascript libraries.

https://backbonejs.org/ then?

We have some backbone actually… https://core.trac.www.ads-software.com/ticket/24424 is that what you mean?

Yes, that is precisely what I meant. ??

Now I know it was updated in trunk to the most recent version but I only seem to see the minified versions of them both in the includes/js folder.
