    Ruby supports both Strings & Symbols.
    String being mutable & Symbols being immutable cater to different needs.

    We can convert String to Symbol & Symbol to String at any time.

    To convert a string to a symbol, we can use intern method or to_sym method which are aliases to each other.

    ex:- (using intern method)

    >> a = "taran"
=> "taran"
>> a.class
=> String
>> b = a.intern
=> :taran
>> b.class
=> Symbol

    (using to_sym method)

    >> a = "taran"
=> "taran"
>> a.class
=> String
>> b = a.to_sym
=> :taran
>> b.class
=> Symbol


    To convert a Symbol to a String we can use the to_s method

    >> b = :car
=> :car
>> b.class
=> Symbol
>> a = b.to_s
=> "car"
>> a.class
=> String
    RAILS symbol string symbol to string string to symbol to_sym intern
