IEx also provides us with another incredibly helpful built-in function: h. Similar to i, h has two arities available for us to use: h/0, which displays the help page for IEx, and h/1, which displays the help for a particular module. So, while the following example won't work:
iex(5)> h 5Invalid arguments for h helper: 5
This following example will:
iex(6)> h IntegerIntegerFunctions for working with integers.
Using i and h effectively will go a long way towards helping us understand more of Elixir as we go along!
