Input

Create a file named app.exjs, add the following and save it:

defmodule App do

  def hello() do
    "Hello, World"
  end

  def hello(name) do
    "Hello, #{name}"
  end

end

One thing to notice is the file extension. Elixirscript files have .exjs as their file extension.

Next, we will compile our file and look at the output.
