What is scope and context in Ruby?

What is scope and context in Ruby?

In Ruby, scope refers to the visibility of variables, while context refers to the object that is currently executing the code.

Can you explain the difference between local and instance variables?

Sure! Local variables are defined within a method and are not accessible outside of it, while instance variables are prefixed with '@' and are accessible across methods in the same object.

What happens if I try to access a local variable outside its scope?

If you try to access a local variable outside its scope, Ruby will raise a NameError, indicating that the variable is undefined.

How does context affect method calls in Ruby?

Context determines which object the method is called on, affecting how instance variables and methods are accessed.
