Best way to quickly test run an .exs file

i too am a new Elixir programmer and here is what i do:

Write your function and all that function as explained below

defmodule Example do
  def add_numbers(num1, num2) do
    num1 + num2
    |> inspect
    |> IO.puts 
  end
end
Example.add_numbers(2, 3)

Save the file with .exs and to run/test use command from a command shell
elixir FILENAME.exs

Hope this helps

Also, you can just alias the module directly into iex and call this function directly there. You don’t need to create another file just to run this manually.

You can also take a look at this require IEx; IEx.pry to understand how is your function behaving at every step. or you can use IO.inspect().

thanks for the awesome information.
