I have used Node.js extensively. In that environment, as I'm sure you know, a module exports one thing. It can be an object with lots of properties on it, a single function, or a single value. I suppose you could say that all Node has is a "default" export which is the one thing the module exports.
I'm trying to understand how that compares to ES6 modules. I see how in ES6 I can import specific things from a module or I can import everything a module exports. Am I correct that a "default" export can be somewhere in the middle ... a subset of everything that is exported?
