What are the different variable types in Ruby?
In Ruby, there are several variable types: local variables, instance variables, class variables, and global variables.
Can you explain what local variables are?
Local variables are defined within a method or block and can only be accessed within that scope.
What about instance variables?
Instance variables are prefixed with '@' and are used to store data specific to an instance of a class.
How do class variables differ from instance variables?
Class variables, prefixed with '@@', are shared among all instances of a class, while instance variables are unique to each instance.
