Create A List Of Atoms
elixir
Written May 22, 2017
The ~w sigil makes it easy to create a word list -- a list of strings --
where each word is separated by a space.
> ~w(bulbasaur charmander squirtle)
["bulbasaur", "charmander", "squirtle"]
By appending an a onto that sigil construct, you are instructing Elixir
that you would instead like a list of atoms.
> ~w(bulbasaur charmander squirtle)a
[:bulbasaur, :charmander, :squirtle]
