The CoffeeScript docs state that list comprehensions should be able to do the select/filter operations:

They should be able to handle most places where you otherwise would use a loop, each/forEach, map, or select/filter.

You'd imagine you could do something in one line like result = item for item in list if item % 2 == 0 However the closest I can come is

list = [1,2,3,4]
result = []
for item in list
  if item % 2 == 0 then result.push item

Whats the most concise way to filter a list in CoffeeScript?
