What are immutable data types in Ruby?
In Ruby, immutable data types are objects that cannot be modified after they are created. Examples include symbols and strings.
Can you give me an example of an immutable object?
Sure! A symbol in Ruby, like :my_symbol
, is immutable. You can't change its value once it's created.
What happens if I try to modify an immutable object?
If you try to modify an immutable object, Ruby will create a new object instead of changing the original.
Why are immutable data types useful?
They are useful for ensuring data integrity and can lead to performance improvements in certain scenarios.
