Trevor looks at a practical use of using such a notebook environment for data exploration. Trevor Manz

👍 Bare: A New Lightweight Runtime for Modular JS Apps Imagine something like Node.js but really stripped back: bare, if you will. Like Node, it’s built on top of V8 and libuv (though it's designed to support multiple JavaScript engines) but Bare’s approach is to provide as little as possible (a module system, addon system, and thread support) and then rely upon userland modules that can evolve independently of Bare itself. It’s an interesting idea – more details here. Holepunch
