FizzBuzz in Javascript using pattern-matching library Funcy (https://github.com/bramstein/funcy). Inspired by this Clojure example: https://github.com/clojure/core.match.

funcy-fizzbuzz.js

var fun = require('funcy')
  , _ = fun.wildcard
  , n;
for (n = 1; n <= 100; n++) {
  console.log(
    fun(
      [[0, 0], function() { return 'FizzBuzz'; }],
      [[0, _], function() { return 'Fizz'; }],
      [[_, 0], function() { return 'Buzz'; }],
      [_, function() { return n; }]
    )([n % 3, n % 5])
  );
}
