Data validation before serialization ensures that the data is accurate and conforms to expected formats before it's converted into a storable format.

Why is it important to validate data before serialization?

Validating data helps prevent errors, ensures data integrity, and avoids issues during deserialization, which can lead to application failures.

Can you give me an example of data validation?

Sure! For instance, checking if a user's email address is in the correct format before serializing it into JSON.

What tools can I use for data validation?

You can use libraries like Joi, Yup, or even built-in validation features in frameworks like Django or Express.
