Having coded in javascript for 4 or so years, and a recent love for NodeJS in a couple of internal projects, I'm a bit torn between giving coffee a proper go or not. Can any one employee give a gist of how used it is in production? From what I've seen I would love to use coffee (I've actually used coffee in reverse, to tweak out a javascript function), but I'm wondering if I'd be lowering my productivity. What I mean by that is, if I wrote coffeescript, but everyone else worked in javascript (or compiled coffee), then it'd be silly of me to continue doing so. Similarly I've watched a lot of node module development over the past year, and only once I've come across a module written in coffee. I do of course realize NodeJS in itself is not "very" widespread yet, but are there any node users who can shed some light on the possible future of coffee in node?
