 module Gargantext.Utils.List where
 
 import Data.Ord (class Ord, comparing)
-import Data.List as List
+import Data.List  as List
+import Data.Array as Array
+import Gargantext.Prelude

 sortWith :: forall a b. Ord b => (a -> b) -> List.List a -> List.List a
-sortWith f = List.sortBy (comparing f)
+sortWith f l = Array.toUnfoldable $ Array.sortBy (comparing f) $ Array.fromFoldable l
