CommonJS, I Promise
summary
Notes what CommonJS actually delivered: modules implemented by Node become the widest deployment, a buffer/binary spec inspired by Node codifies real-world buffers, and a concrete promise API — Q deferred/q.when — gets examples that compose timeouts, HTTP retry loops and reduce-based joins. Packages remain experimental with three major packaging approaches (overlay, npm symlink, registry/linking) and a stopgap Packages 1.0 for metadata. Several implementations exist (Node, Narwhal, browser) and the promise and queue utilities demonstrably work across them.
