Erlang vs node.js 16 years ago
I have to agree, speaking as a programmer just starting to get comfortable in Javascript with little to no experience in more established functional programming languages. The initial wow factor of having javascript on the server and client side quickly gave way to all the reasons to use alternative approaches.
This project will be the first time many Javascript programmers will brush up against topics of scale such as these, and speaking as one, I'm definitely going to focus on Erlang to explore these problems. (but still play around with Node.js on the side ;)
