 In Elixir, all datatypes evaluate to a _truthy_ or _falsy_ value when they are encountered in a boolean context (like an `if` expression). All data is considered _truthy_ **except** for `false` and `nil`. In particular, empty strings, the integer `0`, and empty lists are all considered _truthy_ in Elixir.
