Elixir - Looping through and adding to map

Question

I\'m rebuilding something in Elixir from some code I built in C#.

It was pretty hacked together, but works perfectly (although not on Linux, hence rebuild).

Answer 1

I am also new to Elixir but here is a cute and simple solution that uses pattern matching and recursion.

defmodule YourModule do
   def reduce_list([], reduced) do reduced end

   def reduce_list([first | rest ], reduced) do
      # Do what you need to do here and call the function again 
      # with remaining list items and updated map.
      reduce_list(rest, Map.put(reduced, first, "Done"))
   end
end 

And call the function with just the list you want to map and an empty map

> YourModule.reduce_list(["one", "two", "three"], %{})
  %{"one" => "Done", "three" => "Done", "two" => "Done"}
