5 sourcesVery cool! You might also want to check out sparkler, which uses macros to let you do this with a little better syntax: https://github.com/natefaubion/sparkler
In Pun: A small library to enable pattern matching in JavaScript and CoffeeScriptI don't do a ton of js programming, but I did poke around with cs a bit. For me, clean iteration seemed like the biggest win. And then I discovered underscore/lodash. So I don't do as much cs anymore.
Essentially, js isn't all that busted. The busted parts can for the most part be worked around with underscore/lodash and sweet.js (for the really ambitious)
sweet.js

pretty neat pattern matching library written with sweet.js

I do most of my work in Python, so the above experiences and biases may be a direct result thereof.
