Not the fastest implementation, but it is readable:

numbers = [1, 2, 3]
sum = 0
sum += num for num in numbers

Note the similarity to the other answer. This is the correct syntax, and it is identical to:

numbers = [1, 2, 3]
sum = 0
for num in numbers
  sum += num

numbers = [1, 2, 3]
sum = 0
(sum += num for num in numbers) # add each number in array to sum

The easiest way is probably to use Array.prototype.reduce just like you'd do in JavaScript:

numbers = [1..11]
sum     = numbers.reduce (m, n) -> m + n
# sum is now 66
