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?
