This is an initial attempt at gathering together up to date resources on ES6 modules.
- The ES6 draft spec has an up-to-date grammar and list of early errors. It's not the easiest thing to read, but is the most authoritative.
- This informal grammar summary is pretty good, and starts to explain how default exports work.
- These two comments in sequence give examples of all the import and export forms available.
- jorendorff/js-loaders is a polyfill for the module loader API and pipeline, and is where current work is taking place.
- This essay is out of date in many ways, but I believe its explanation of the loader pipeline is still more or less accurate. To be sure you'd have to check it agai
