% perform M runs with N calls to F in each run. % For each of the M runs, determine the average time per call. % Return, the ave erlang. You might want to read about this issue in the Erlang efficiency guide, since there it says that building the list via | and then reversing the result is more efficient than using the appending ++ operator. If you want to know the performance difference, use timer:tc: 1> timer:tc(fun() -> Currently you can use maps module to implement count_characters: count_characters(Str) -> count_characters(Str, #{}). count_characters([H|T], X) -> count_characters(T, maps:put(H, maps:get(H, X, 0) + 1, X)); count_characters([], X) -> X. For now (Erlang R17) there is no way to use variable directly in map expression. You can achieve this with maps: new and put : nested_func(maps:put(K, V, maps:new())) Because Erlang maps respect Erlang sorting order, a map such as # {1.0 => true} is going to compare equal to # {1 => true}, but you won't be able to match them one against the other.

My question is that Is it possible limit the map types of key and value ? Variables are bound to values using pattern matching.Erlang uses single assignment, that is, a variable can only be bound once.. The anonymous variable is denoted by underscore (_) and can be used when a variable is required but its value can be ignored. double(L) -> map (fun (X) -> 2 *X end, L). add_one(L) -> map (fun (X) -> 1 + X end, L). map (F, List) is a function that takes a function F and a list L as arguments and returns a new list, obtained by applying F to each of the elements in L.
