This works:
[1 to 10] |> filter (> 4) |> console.log #[ 5, 6, 7, 8, 9, 10 ]
This works:
empty {} #true
but this doesn't:
[{"foo"}, {"bar"}, {}, {}] |> filter empty |> console.log # [ { foo: 'foo' }, { bar: 'bar' }, {}, {} ]
[{"foo"}, {"bar"}, {}, {}] |> map (-> console.log (empty it) ) #true true true true
Is this a problem with empty?
Any help will be appreciated.
My current workaround is to implement my own empty:
empty = (obj)->
Object.keys(obj).length is 0
You need to use the appropriate empty function for the type of input you are using, in this case, use Obj.empty. The empty you are using comes from List.empty. Using that on an object should probably be an error instead of what currently happens.
[{"foo"}, {"bar"}, {}, {}] |> filter Obj.empty
