special-considerations
Special considerations:
- Elixir built-in data types to work with: binary, nil, integer, float, atom, list, map, boolean.
- Elixir's non-built-in data types to work with: DateTime
- Elixir non-existent data types, but need to create its name:
- string: Binary equivalent.
- string_datetime: Equivalent to converting from an integer to a binary, in DateTime format.
