Atoms
Representation
An atom is a constant which name is its value. Every atom starts with colon and ends with word or operator known for Elixir. Things to remember when creating an atom:
must be a sequence of UTF-8 letters,
might consist of digits,
might include the underscore,
might include @,
might end with ? or !,
can be created with any string when enclosed within quotes.
Example of atoms:
:hello, :"hello world", :+, :===, :exists?
Two atoms with the same naming always represent the same value.
iex> :hello == :hello
true
iex> :hello == :"hello"
true
iex> :hello == :"hello world"
false
You can check if given value is atom with is_atom/1 function:
iex> is_atom :hello
true
iex> is_atom "hello"
false
iex> is_atom :"hello"
true
You'll be using atoms very often to tag values.
