What is versioning in deserialization?

Versioning in deserialization refers to the process of handling different versions of data structures when converting data from a serialized format back into an object. This is crucial for maintaining compatibility as data formats evolve.

Why is it important to manage versions during deserialization?

Managing versions is important to ensure that your application can correctly interpret and use data, even if the data structure has changed over time. It helps prevent errors and data loss.

Can you give an example of how versioning works in deserialization?

Sure! For instance, if you have a user object that originally had fields for 'name' and 'age', and later you add a 'email' field, versioning allows you to handle both old and new user objects without breaking the application.

What are some common strategies for implementing versioning?

Common strategies include using version numbers in your data format, maintaining backward compatibility, and using default values for new fields in older versions.
