IEx.Helpers

Welcome to Interactive Elixir. You are currently seeing the documentation for the module IEx.Helpers which provides many helpers to make Elixir’s shell more joyful to work with.

This message was triggered by invoking the helper h(), usually referred to as h/0 (since it expects 0 arguments).

You can use the h/1 function to invoke the documentation for any Elixir module or function:

iex> h Enum
iex> h Enum.map
iex> h Enum.reverse/1

You can also use the i/1 function to introspect any value you have in the shell:

iex> i "hello"
