Mildly pedantic way to take command line arguments, coerce into numbers and then add them up.
Raw
gistfile1.coffee
add = (nums) ->
result = 0
for n in nums
result += n
return result
nums = []
for arg in process.argv[2..]
arg = Number(arg)
nums.push(arg)
console.log(add(nums))

Even more pedantic:

sum = (list) ->
  [mine, rest] = [parseInt(list[0]), list.slice(1)]
  return (if not rest.length then mine else mine + sum(rest))

console.log(sum(process.argv.slice(2)))
