title: Using an external functional language for data processing in node.js
body: <p>I'm working on a project that at some places would benefit greatly in code cleanliness if the problems were solved in a functional style. Now, Javascript is for the most part fully capable of doing functional programming, but I find that syntax gets in the way more often than not. The parentheses, having to write <code>function</code> and stuff like that.</p>
  
  <p>So I'm looking for a way to somehow use a different language for those parts of the code. Either an embedded language that compiles to JS or an external scripting language with good interoperability.</p>
  
  <p>Are there any existing solutions to this?</p>
