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
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])
