17. An immutable data type is one that cannot change after being created. Give three reasons to use immutable data.

Three reasons to use immutable data types:

1. Thread safety: Immutable data types are inherently thread-safe because they cannot be modified, reducing the risk of data corruption in concurrent environments.
2. Cache optimization: Immutable data types can be cached more effectively, as their values are constant and can be reused across multiple parts of the program.
3. Easier debugging: Immutable data types simplify debugging by eliminating the possibility of unintended changes to data, making it easier to reason about program behavior.
