14. STANDARD LIBRARY

15. STREAMS

16. STREAMS "foo.txt" |> File.stream! |> Stream.map(...) |> Stream... |> Enum.to_list

17. METAPROGRAMMING

18. defmacro unless(cond, expr) do quote do if !unquote(cond) do unquote(expr)

    end end end

19. defmacro unless(cond, expr) do quote do if !unquote(cond) do unquote(expr)

    end end end

20. STRUCTS "official" data types

21. defmodule User do defstruct [:name, :age] end %User{name: "Meg", age:

    33}

22. PROTOCOLS

23. JSON encoding json:encode({user, ...}) user:encode({...})

24. JSON encoding defprotocol JSON do def encode(_) end defimpl JSON,

    for: User do def encode(user), do: ... end

25. ExUnit test "send/2" do send(self(), {:ok, 1}) assert_receive {:ok, _}

    end

26. ExUnit test "send/2" do send(self(), {:ok, 1}) assert_receive {:ok, _}

    end

27. tagging diff --stale

28. None

29. --stale don't run stale stinky tests

30. INTEROP WITH ERLANG for doing Real Work™

31. lists:map(fun(X) -> X + 1 end, [1, 2, 3]) :lists.map(fn(x)

    -> x + 1 end, [1, 2, 3])

32. Enum.shuffle([1, 2, 3]) 'Elixir.Enum':shuffle([1, 2, 3])

33. MIX

34. DOCUMENTATION @doc """ Performs command """ def command(c), do: ...

35. DOCUMENTATION

36. ONBOARDING Getting Started guide Resources (books, ...) Error messages

37. ECOSYSTEM Phoenix Nerves Ecto, Plug, GenStage, ...

38. COMMUNITY

39. GOOD STUFF IMPROVABLE STUFF ELIXIR + ERLANG

40. DIALYZER

41. PROPERTY-BASED TESTING

42. USING ELIXIR FROM ERLANG

43. GOOD STUFF IMPROVABLE STUFF ELIXIR + ERLANG

44. just an app

45. WHICH ONE DO I USE ELIXIR ELIXIR ELIXIR ELIXIR ELIXIR

    ELIXIR ELIXIR

46. APPRECIATE BOTH

47. POSSIBLE RULE OF THUMB libraries in Erlang (if they wouldn't

    benefit from Elixir features) apps in Elixir /

48. hex.pm Erlang + Elixir

49. GOOD STUFF IMPROVABLE STUFF ELIXIR <3 ERLANG STDLIB EXUNIT METAPROGRAMMING

    PROTOCOLS MIX DOCS ECOSYSTEM DIALYZER PROPERTY-BASED TESTS ELIXIR FROM ERLANG USE BOTH SHARE ON HEX BE NICE
