Use Kernel.inspect to convert anything to string. iex> Kernel.inspect(1) "1" iex> Kernel.inspect(4.2) "4.2" iex> Kernel.inspect %{pi: 3.14, name: "Yos"} "%{pi: 3.14, name: \"Yos\"}"

iex> my_string = "Lorem ipsum dolor sit amet, consectetur adipiscing elit." iex> String.slice my_string, 6..10 "ipsum"

iex> String.split("Elixir, Antidote, Panacea", ",") ["Elixir", "Antidote", "Panacea"]

iex(1)> name = "John" "John" iex(2)> greeting = "Hello, #{name}" "Hello, John" iex(3)> num = 15 15 iex(4)> results = "#{num} item(s) found." "15 item(s) found."

iex(1)> String.contains? "elixir of life", "of" true iex(2)> String.contains? "elixir of life", ["life", "death"] true iex(3)> String.contains? "elixir of life", ["venus", "mercury"] false
