symbols is placeholders for identifiers and strings.


# You can recognize symbols because they are always prefixed by a colon (:).
# You don't directly create a symbol by assigning a value to it. 
# You create a symbol by calling the to_sym or intern methods on a string or by assigning a symbol to a symbol. 


name = "myValue"
name.to_sym # => :myValue
:myValue.id2name # => "myValue"
name == :myValue.id2name # => true
