What is the difference between mutable and immutable data types in programming?
Mutable data types can be changed after they are created, while immutable data types cannot be modified.
Can you give me examples of each?
Sure! Lists in Python are mutable, while tuples are immutable. In Java, String is immutable, but StringBuilder is mutable.
Why would I choose one over the other?
Choosing mutable types can be beneficial for performance when frequent changes are needed, while immutable types can enhance safety and simplicity in concurrent programming.
Are there any programming languages that only use immutable data types?
Yes, languages like Haskell and Scala emphasize immutability, promoting functional programming principles.
