I've seen that project before starting combinatorics.js. It is a useful library, however, I felt that it was a little basic for what Combinatorics research needs. I would like to dive deeper, implementing such objects like Posets, Paths (Dyck paths and the like), and enumerative sets. js-combinatorics is a great starting point though.
