What is the difference between JSON serialization and deserialization?

JSON serialization is the process of converting an object into a JSON formatted string, while JSON deserialization is the process of converting a JSON formatted string into an object.

The specific differences are as follows:

1. JSON serialization: converting an object into a string in JSON format. During the serialization process, the object’s properties and values are transformed into JSON format, and certain properties can be included or excluded selectively. Common methods include JSON.stringify().
2. JSON deserialization is the process of converting a JSON-formatted string into an object. During deserialization, the JSON string is parsed and converted into the properties and values of the object. A common method for this is JSON.parse().

In summary, JSON serialization converts objects into strings, while JSON deserialization converts strings into objects.
