It's usage mirrors Html.App or Navigation modules' program* functions, for example instead of: im...

> List.repeat 3 "abc" ["abc","abc","abc"] : List String You can give List.repeat any value: > List.repeat 2 {a = 1, b = (2,True)} [{a = 1, b = (2,True)}, {a = 1, b = (2,True)}] : List {a : Int, b : (Int, Bool)}

By default, List.sort sorts in ascending order. > List.sort [3,1,5] [1,3,5] : List number List.sort needs the list elements to be comparable. That means: String, Char, number (Int and Float), List of comparable or tuple of comparable. > List.sort [(5,"ddd"),(4,"zzz"),...

List.sortWith allows you to sort lists with data of any shape - you supply it with a comparison function. compareBools : Bool -> Bool -> Order compareBools a b = case (a,b) of (False, True) -> LT (True, False) -> GT _ -> ...

Note: this is not very efficient due to the nature of List (see Remarks below). It will be better to construct the list the "right" way from the beginning than to construct it and then reverse it. > List.reverse [1,3,5,7,9] [9,7,5,3,1] : List number

By default List.sort sorts in ascending order, with the compare function. There are two ways to sort in descending order: one efficient and one inefficient. The efficient way: List.sortWith and a descending comparison function. descending a b = case compare a b of LT -> GT ...

List.sortBy allows to use a function on the elements and use its result for the comparison. > List.sortBy String.length ["longest","short","medium"] ["short","medium","longest"] : List String -- because the lengths are: [7,5,6] It ...
