Seriously, CoffeeScript is amazing. I've been working on a large client-side project in CoffeeScript for the past few weeks and every time I look at the resulting JS output I can't imagine having written it by hand; it's been a massive boon to my productivity. I wrote JavaScript for years before this and hated it at times, and now I can't ever imagine going back if given the choice.
CoffeeScript is much easier to read than javascript, that alone is a blessing. Admittedly I haven't used coffeescript much yet, I just cranked it up with nodemon a couple of weekends ago. I need a good starter coffeescript project that works on the backend with node, and the client side.
