Enum – Elixir v1.1.1

Elixir v1.1.1 Enum Provides a set of algorithms that enumerate over collections according to the Enumerable protocol: iex> Enum.map([1, 2, 3], fn(x) -> x * 2 end) [2, 4, 6] Some particular types, like dictionaries, yield a specific format on enumeration. For dicts, the argument is always a {key, value} tuple: iex> dict = %{a: 1, b: 2} iex> Enum.map(dict, fn {k, v} -> {k, v * 2} end) [a: 2, b: 4] N
