module.exports = and ES6 Module Interop in Node.js

The question: how can we use ES6 modules in Node.js, where modules-as-functions is very common? That is, given a future in which V8 supports ES6 modules:

• How can authors of function-modules convert to ES6 export syntax, without breaking consumers that do require("function-module")()?
• How can consumers of function-modules use ES6 import syntax, while not demanding that the module author rewrites his code to ES6 export?

@wycats showed me a solution. It involves hooking into the loader API to do some rewriting, and using a distinguished name for the single export.

This is me eating crow for lots of false statements I've made all over Twitter today. Here it goes.

true and false vs. "truthy" and "falsey" (or "falsy") in Ruby, Python, and JavaScript

Many programming languages, including Ruby, have native boolean (true and false) data types. In Ruby they're called true and false. In Python, for example, they're written as True and False. But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).

This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too. The idea is much more general than any of these specific languages, though. It's really a question of how the people designing a programming language wants booleans and conditionals to work.
