In Ruby, if one were defining constants in classes, they would define them using all caps. For example:

class MyClass
  MY_FAVORITE_NUMBER = 13
end

How do you do this in Elixir? And if no such equivalent exists, how do you get around the problem of magic numbers in Elixir?

You can prepend your variable name with @:

defmodule MyModule do
  @my_favorite_number 13
end

Here are the docs
