Posting to establish the hashtags I guess.
One of the things I work on at #Dfinity is the #Motoko #programming language, which we could also tag as #MotokoLang
It's a type-safe language designed to compile to #WebAssembly, and is used for smart contract development.
There's a good package manager at https://mops.one/ that I've been using in my projects, and I've written a few packages myself: https://mops.one/search/owner:kai
Personally, I think it's a pretty nice balance of a low-level interface, but one that feels familiar, as a #TypeScript engineer. I specifically wrote the https://mops.one/server library to resemble the patterns of Express.js, and find it pretty fun to work with, when I find the time for backend development
