JS.Next and CoffeeScript
summary
Claims that ES6 ideas are arriving and that CoffeeScript already gives practical fixes for real web constraints, with a compiler that compiles down to ES3 so code runs on old browsers. Examples include classes, destructuring assignment, and lexical vs dynamic this via fat arrow and thin arrow functions. Notes real-world constraints: many newsroom graphics have a 24 hour lifespan so tooling must produce small, defensive code. The CoffeeScript compiler is itself implemented in CoffeeScript and spawns many forks.
