What is the best way to combine multiple data types (such as String, Int, Date, and List) into a single variable for storage?

The best way to combine multiple data types into a single variable for storage is by creating a custom data structure or object that contains fields for each data type. For example, if you need to store a person's name (String), age (Int), birthdate (Date), and hobbies (List), you could create a Person object with fields for each of these data types. This allows you to organize the data logically and access it easily when needed. Alternatively, you could use a data serialization format such as JSON or XML to store the data in a structured way.
